I once rode in a car with someone I had never rode with for a short roadtrip. On the highway, pushed their foot on the accelerator for 1-2 seconds, then let off the accelerator for 1-2 seconds, for the WHOLE 35 MINUTES on the interstate.

You noticeably felt the acceleration, and then felt the fall back from lack of gas. THE WHOLE WAY.

I am not one to get carsick. I was getting carsick. Had a few opportunities to ride with them again, I declined.

I was driving in slow traffic (just slow moving, not completely stop and go) and I heard behind me and to the right this VROOOM... pause.... VROOOM....pause....

Eventually the noise comes up beside me and of course dude's on his cell phone, 3 or 4 car lengths behind the guy in front of him. All of a sudden VROOOOM and then he's right up on the guy in front of him, and slams on the brakes (he was moved forward in his seat pretty violently from the braking). His lane continued to pass mine for a while, the whole time he's either not accelerating at all, or just barely avoiding smashing into the guy in front of him.

I think I would go insane if I had to ride with him (although I don't ride with people who use the phone while driving) or got stuck behind him.

I fucking hate people who are on their phones while they're driving. They're either slow, dangerous or both. I can't count the number of times when someone's impeding traffic all around them and it turns out they're on their phone.

People who swerve in and out of their lanes, drive erratically, they're slow, almost rear-end people, camp in the left lane, I fucking hate them all. I feel like I need to see a professional about the murderous rage I get when I see someone looking at their cellphone instead of the road, oblivious to the traffic jam they're creating behind them.

Still have no understanding how that's even legal. It's completely illegal to even hold your phone (or any electronic device) whilst driving here. Even if you're using it for GPS etc (as I do), it must be secured in a way that doesn't need a hand to hold can touch it (providing you're not distracted), but you're not allowed to physically hold the device...yet I hear of Americans actually sitting driving with tier phone in their hand, looking at it instead of the road etc. Gee, wonder why road deaths are higher....

California even got fed up with the whole holding a phone while using GPS loophole. Now all phones must be mounted on a dash-mount if you want to use it in the car.

I live in California. People still drive AND talk on their phone with their PHONE NEXT TO THEIR EAR. I see it alll the time. Aghhh

And next to a cop that doesn't pull them over so nothing will change.

CA law is a fucking joke.

It could have been a manual. In steadily slow traffic, often 1st gear is too fast for traffic speed without using the brakes. He may also not be very experienced in a manual, revving the gas before letting out the clutch.

Sounds like he needs to learn what the Clutch Point is.

Just leave more room in front of you. Buffer zone baby

Depending on the location, that might encourage people to cut you off. From slower lanes in traffic.

The kind of angry petty drivers that don't use turn signals and cause car crashes.

Just slow down until the gap is bigger again.

I'm never in such a hurry that I'm alright with losing my life.

Omg idk how people drive dude. They go 90 miles to shave 2 seconds off their trip. They ride the shit out of every car in front of them. If they even have to go lower than 70 they audibly sigh and start looking around to see if they can change lane

You can go 90 and drive safe. Maintaining distance, slowing down to pass, etc.

Shit you can go 125mph if you just do those things. Its like people just shut off the 90% of their attention to the road and it makes everything slower.

If you’re driving a manual you definitely shouldn’t be on your phone.

I heard some people can smoke and drink coffee while making a left turn and shifting in a 30 year old car with no cupholders or auto cancelling signals and a shitty clutch.

I would personally never do such a thing, though.

But can you do it all while drifting and without spilling the water?

Yep, that's my mom driving. I rarely get sick, in a car, plane, boat in choppy water, but I always get sick driving with her.

My mom too. I’ve called her out on it and she always says “that’s the way I was taught in drivers ed, you’re supposed to pump the gas.” I know she’s confusing pumping the gas with pumping the brakes which I believe was taught before abs when you need to avoid skidding out. It’s infuriating.

She may also be confusing pumping the gas for when you're starting a cold carbureted car which she may be old enough to have learned on.

Or maybe she's thinking of "pumping the gas" at the gas station, which you have to do every week or so, otherwise the car will quit.

That's terrible for gas mileage

1.3k points · 6 months ago · edited 6 months ago

There's actually a hypermiling technique called "pulse and glide" that nets you better fuel economy over time by spending half your time accelerating up to a certain speed and the other half of your time coasting down to a lower speed, and repeating.

EDIT: A lot of you are contesting this; some of you are chiming in in support of my claim. So here's more fuel for the fire: a lengthy tutorial on hypermiling, written by yours truly.

Was in a prius with someone who did this. They also drafted behind a semi truck. I highly considered jumping out the window.

Oh man - they must be that kind of Prius owner who will brag about the MPG they got last month.

I have a Prius, totally not worth the time to achieve the best mpg.. I can drive like a madman and get Subaru STi on the other hand..if I drive like I stole it gets a wonderful 16mpg (19 at best).

80 points · 6 months ago

Everyone loves to rag on the Prius but 45+ mpg driving normally and brake pads that last 50k+ miles? Sign me up.

To be honest I don't even use the brakes much. I spend a lot of time coasting or I use mountain mode, B gear. If anything I tap the brakes to trigger the taillights for safety and then coast/mountain mode. But anyway, not a bad little car. When I've got the itch for speed I take the STi out for a spin.

23 points · 6 months ago

IIRC B mode doesn't really help with gas mileage. Some good read here:

As for brakes, I think driving a Prius permanently makes me anticipate how much distance to brake ahead of a stop, with more gradual stops.

MPG is pretty shitty of a metric anyways. It doesn't really show the diminishing returns. Flipping it and doing Gallons Per Mile (really g/100mi) is much better.

  • So a 10mpg car uses 10g/100m.

  • A 20mpg car uses 5g/100m.

  • A 30mpg car uses 3.3g/100m.

  • A 40mpg car uses 2.5g/100m.

  • And a 50mpg car uses 2g/100m.

You can see that as your mpg gets higher the actual gas saved per 100m travelled gets progressively smaller. Every 10mpg up you go saves you 5, 1.7, 0.8, 0.5 gallons. Eventually getting a higher MPG is saving you pennies instead of dollars.

Works best for hybrids... Not for gas only vehicles on a flat road. Hills.. may be a different story

490 points · 6 months ago · edited 6 months ago

It's shit for EVs as well, pulseglide is really only great for the hybrids that happen to fit that weird middle.

I think all cars on hills are better off just gliding as much as possible for the down section and keeping the power band as average as possible on the way up, there's a mountain in Hawaii that you can drive down for almost an hour and recharge 40 miles more than you started with at the top just by letting the regen brakes do their thing, but you exchange a lot of that going back up.

You exchange more than all of it going up if you're going up the same mountain.

You’ll end up exchanging more than that on the way up if it’s the same mountain

42 points · 6 months ago · edited 6 months ago

You do use a lot more than average going up! It's not that bad though, considering the total trip energy use is only the up trip minus 43 miles or so, there is no down cost and the down actually subtracts from the up. It's "free" energy because nothing at all is spent on the downhill, that all comes from gravity and the excess goes into that energy spent on the way up.

The neat part of hill climbs in an EV is you can see ICE vehicles falling off in performance as the air thins, but the EV just doesn't. You only notice the grade of the road is increasing when you look at the energy gauge and see its numbers are climbing.

The law of conservation of energy suggests that you will use more energy climbing, as some will be lost to heat and sound and such. Unless you are also charging using a solar panel, you can't possibly get more energy coming down a mountain than you used going up.

Correct. When I say "it's not that bad" I mean against a gasoline car that burns both ways instead of recouping a portion of the up trip for the down half. You still double burn on the way up no matter the vehicle. In my garage we obey the laws of thermodynamics!

Years ago I saw this old couple on TV who had broken some kind of record for gas mileage and were hoping to do it again with different tires designed just for that.

The lady doing the interview asks "so what would you recommend as the best way to increase mileage?"

This old lady blurts out "drive 10-15 miles below the speed limit."

How she was still alive after doing that is beyond me.

Perhaps she lives in the middle of nowhere?

Two-lane highways in a rural area.

Heck, I drove 10-15 slower when I was driving through Nowhere, Wyoming, provided there was no traffic around. That put me at 60-55 - the norm for where I'm from. Fuel economy went up dramatically.

You just need to time your speed so friction from the road will slow your car before you reach the red light.

But then also not drive slow and be an asshole/hazard

(For all those readers who want to try hypermiling) Within reason. Don't be coasting at 10mph when you're 400 feet away from the stop light.

oh god. Sometimes I have to ride with someone like that too. Constantly slamming the gas and brake like someone who just got their learner's permit. Floors the gas every two seconds for no reason and then lets off over and over. Jerks the steering wheel around incessantly like we're driving through a mine field, even on perfectly straight roads. Can't maintain a lane worth a damn. Fooling around with his phone for literally minutes at a time like he's trying to read a novel while driving. Waiting until the last possible second to slam on the brakes at every. single. stop.

And the funny thing is, this guy is way older than me and has tons more driving experience than I have. You'd think after decades of driving that someone would know how to operate a vehicle with at least a little finesse. I guess some people never learn.

Once after being at the ER for a dislocated hip I was getting discharged sooner than expected so my dad came to pick me up instead of my mum and I was so upset, the nurses lecturered my dad for showing up in a truck, he had to lift me into the seat. He drives like a chicken bobbing it's head as it walks. We barely got halfway down the road before I was like "turn around, go back, my hip is out again" he was not impressed with my hip, I was not impressed with his driving. By the time I was ready to go home again my mum was free to pick me up in her tiny car and she drives like oil on butter.

That, and people who keep hitting their brakes even though there's no one in front of them. YES,YOUR GODDAMN BRAKE LIGHTS WORK!

RE-EDIT because apparently I wasn't clear enough: Based on some of the replies I'm getting, there's a couple things I need to clarify. No, I'm not tailgating them. Nobody is tailgating them, because most of the time there's not even somebody behind them and I'm watching them do this from a completely different lane They're also not going down hill. I usually see this on straight and level stretches of road. Hell, one time I was driving near a guy whose brake lights were illuminated for at least a quarter mile. Finally, they're not using cruise control. If they were using cruise control, they wouldn't need to hit the brakes repeatedly every 4-7 seconds.

TL;DR they're just driving defensively. They're just idiots.

EDIT 2: I don't think I'm making this clear enough. This is not a brake check because you can't brake check someone WHEN THERE IS LITERALLY NOBODY BEHIND YOU. Most of the time I'm watching them do this from a completely different lane.

So many people just don't understand that letting off the accelerator slows you down. People just think there is gas and brake.

Or, they just lightly step on the brake to turn on the lights so that you know they are slowing down.
This is what is taught in drivers Ed in Sweden, at least at my school. That is, when using the engine to brake, just step lightly on the break so your brake lights turn on.

Or they're trying to turn off cruise control

9/10 this is it for me.

Cruise control is a blessing.

It's a double-edged sword, I've found. I bought a car with cruise control a little over a year ago specifically because most of my commute is on the motorway. Whilst it's great that now my speed is maintained and I don't even have to think about it, it really highlights how much others vary their speed. There have been occasions where I have overtaken the same car 4 or 5 times on a 20mi stretch of motorway because they keep varying their speed, usually slowing down going up a hill and speeding up going down it. Similarly, catching up with someone who is maybe doing 2-3mph slower then me, then have them speed up and fuck off into the distance as I'm abreast them because we've crested a hill.

It is intensely frustrating. I fucking love driving, always been a petrol head, but I really want the autonomous car revolution to hurry the fuck up.

317 points · 6 months ago · edited 6 months ago

What's that?

Good God what has happened here

Adaptive cruise control? Think of it as autodrive 0.5. There is a radar unit in the front of the car that detects the car in front of you. You engage cruise control, and the car will automatically follow the speed of the person in front of you, adjusting the distance between based on your settings and the speed of travel (if you are doing 80 you have a larger gap than doing 25). You set the maximum speed you want to go, and let the car do the rest.

Mine even does stop and go traffic, so when things get mucked up the car just goes with the flow.

Not impossible at all. I have a manual Cadillac ATS and the cruise control does not stop working when shifting and down shifting. If you had adaptive cruise with a manual that did this it would work.

And I have a sneaking suspicion they think you're the asshole because you keep passing them, not realizing that your speed has been constant the whole time.

Yep, some dude in an AMG Mercedes did that to me on the way to Boston. Have my cruise set to 75 and just cruising along. I catch up to him and signal over a d he speeds up. I signal back to the right and over the next couple miles he slows down again. I signal over to pass and he speeds up. After 3-4 cycles I just say fuck it and gas it to pass him because Jesus, it's fucking annoying. He gives me he finger as I go by so I give him the call me signal. He then tailgates me the next 10 miles.

Money doesn't buy class I guess. Fucking moron.

Cruise or not, assholes like that who speed up the moment they see your signal and attempt to pass are the fucking worst. And they're often the ones who stay in the left lane forever, going under the speed so after the won't let you pass he'll they create the bottleneck of hell.

That was my mom while we were on a short road trip last year. This is the same woman who taught me how to drive and has taken me on many road trips in my youth, but now it's over a decade later. She hasn't figured out how to set the cruise control on her car yet (my dad talked her through it a couple times on the trip and honestly it was like 4 or 5 steps to set it, wtf?). So here we are driving down the interstate, passing people at about 70mph, and then she'll start telling a story or whatever. This distracts her enough to not watch her speed and she'd go down to 60mph. Then someone passes her and she gets all disturbed because that's the person she just passed, why can't they keep a consistent speed? And while she says that's she's slowly accelerating back up to 70mph. This happened over and over and over...

Then you have me in the back seat, trying really hard not to be a backseat driver because I definitely am one, holding my GPS watching the speed drop and increase, wondering what's the best way to say something because she just paid for a mini-vacation and provided transportation. I decided to ignore it.

Always fun to look at driver while passing them, knowing I’ll see him/her again.

I enjoyed that when I had a motorcycle. Sometimes I could find a decent driver going at a decent speed so I'd just sit in his draft. We'd pass and be repassed by the same cars. After a few of those you just have to tuck and twist by them for fun.

I get why you do what you do but this makes me really anxious. It's not exactly tailgating, but close ish.

Oh no. :( Cars too? I always thought you guys were my car buddies on long trips. Like, find one random car that's going +5-10 and just follow him forever until one of you has to leave. Always made me sad. I didn't know it made some people anxious.

You can hit the slipstream up to around 150 feet back in a car. Likely even further on a motorcycle. Not as efficiently as if they were 25-30 feet back though. 50-75 is around where I'll stick.

Don't listen to that guy I always try to find someone to drive with. It always kinda sucks when you spend 100+ miles driving with someone and then you have to part ways. I always try to flash my beams at them before leaving to say goodbye.

Yeah me too. I tend to be overly aware of any motorcycles when they're around me so when they're just sitting behind me I can't really relax

Times like that, it's nice to have a fast car.

By the third time or so, you just say "Fuck you, guy. I'm going to go 120mph for a few minutes, and then I'm never going to see you again in my life. Bye!"

Ya know I was just thinking "I don't go on enough road trips with my attorney"

As your attorney, I recommend we....

...take a hit out of the little brown flask in my shaving kit, and then immediately patent your "cruise control" idea.

I use cruise control as much as possible and it has revealed to me how many other drivers are inconsistent idiots. Oh, hi person I've passed 3 times already on CC, passing me again!

*cruise on

*come up on someone

*move to the left


"the fuck. Fucking maintaining your fucking speed if your'e going to fucking drive. If you wanted to fucking go this fast fucking be going it so I'm not all the way fucking over here when I should just be fucking chilling in the right lane with you god damn right next to me because your brain has latched onto my car speed, let me back in because I'm a lazy SOB-"

*Stomps gas

Or how about the asshole who will match your speed, with them in your blindspot, or with you in theirs. Speed up a bit and they do it again. After a couple rounds of that game I'll floor it just to get the fuck away from them.

I can forgive that for ignorance. Only reason I'm hyper aware of blind spots is because I rode a motorcycle for awhile.

I guess you're more forgiving than me. When traffic is flowing freely there is zero excuse to driving in somebody's blind spot or allowing somebody else to drive in yours.

Situational awareness isn't just for motorcyclists! :)

People match speeds all the time, speeding up when getting passed, slowing down when passing. It's herd behavior.

I've trained myself to deliberately do the opposite. People driving giant hunks of metal right beside me is, uhh, yeah, I would prefer to have some personal space.

Really good way to get a spooky ability to find the part of the highway that's in between two groups of cars and just sit there by yourself.

I call that strategy:
Blast the Packs
Maximize the Gaps.

Get through clumps of traffic as fast as you can, but then when you find a nice empty space between groups, try to maintain it, even it if means slowing down.

SadlyIamJustaHead, I will tell you my cruise control secret for driving on the highway.

Set your cruise to 2KM/MPH UNDER the speed limit. When you do this; 99% of the time you will not catch up to another vehicle.

Which means you no longer need to change lanes, which involves putting on your signal light on, checking your mirrors, checking your blind spot, stopping your cruise control so you don't hit the vehicle in front of you, changing lanes, accelerating to pass the vehicle, and then the same steps to get back in the right lane.

Instead, you get to chill in the right hand lane, relax, listen to music, and turn the steering wheel as nessicary. Almost zero stress caused by other drivers with this method.

In addition, because you won't be passing many other vehicles (Thus speeding up and slowing down) you'll save on gas.

I feel like I'm the only person that does cruise control in the right lane and have people ride my ass with one to three open left lanes. And I'm talking open stretches, not busy on/off areas.

I've had that happen before too. Odds are they are on the phone and completely zoned out. They're following you.

I had a guy follow me to a complete stop on the shoulder doing that.

Try having two lane roads and highways your entire commute with no passing zones that are actually safe to use

Luckily I've recently switched jobs that has me leaving at 3am and driving home at 2pm, the empty highway every morning is a godsend

My cruise control is broken, so now I just go faster than most people. Seems to solve the problem.

I guess I did that before, but it helps in this case.

A cop “clocked” me going 63km/h in a 40km/h school zone. My car has a speed limiter, I always flick it on in school zones. I had the limiter set to 36, no way I was going 63.

I'm sure you can take this to court. Every car has a computer inside of them that you can acquire data from at the specific time and date. It logs everything. Insurance companies use this data for some of their claims sometimes.

I'm going to need a source on that. The OBD2 standard used for most modern cars (of course, newer high model cars may have their own thing), does not log everything. It displays real time data, such as speed, but you need to get a separate device to record that in order to log speed vs time. Logging speed data for most diagnostics would be a waste of memory, and we know how much companies like to use the bare minimum for memory.

Some of the OBD2 parameters available.

The most amazing thing is that the guy who invented it was blind.

60 points · 6 months ago · edited 6 months ago

Very impressive that a blind person invented it, but I'm actually not surprised that a blind person was the first to be annoyed by it enough to want to find a solution. I'd imagine that they are more likely to feel the constant change in vehicle speed since, without sight, it's their only way of getting an idea of speed.

I'd also imagine it is more jarring in a way to not be able to see. I don't really know how to explain it but I'm a sailor and I've always been told not to close your eyes if you're feeling seasick; You'll feel the boat's rocking a lot more. Instead, focus your sight on the horizon to help yourself feel more stable. It just works somehow. For mild seasickness, at least.

This makes me really curious if blind people are more prone to vertigo, and how they would combat it..

what the fuck

This will get buried in the comments but Ralph Tetor did not invent the modern cruise control. My grandfather Frank J. Riley did in 1956 in Mississippi. We have the original patent and everything hanging in our house.

The original story goes, my grandfather invented it in 1956 after being stationed in Mississippi. He felt bad for truck drivers who had to constantly hold the gas pedal down for highway speeds and changes in elevations. He then originally created a design called the AUTO CONSTANT and held the patent for 14 years. He unfortunately never continued to renew the patent as manufacturers did not want any interest in the design.

Along comes mother fn blind Ralphy boy here who says he invented it due to his driver constantly changing speeds. He sold the idea to Cadillac and made some money off it.

My grandfather met him at a auto investor group somewhere along the way and was removed for punching out Ralphy boy who said to my grandfather "Oh, you're the asshole who held us up for 14 years"

Tl;DR: grampa invented cruise control but some blind guy took credit

Here is a source that explains in detail

Edit: just called my mother who explaid that my grandfather didn't punch blind Ralphy boy but rather a Cadillac dealer showing off the cruise control on a floor model.

Edit 2: here's a picture of him for the people calling bullshit

If the first car to use it was in 1958 why did he not sue them for patent infringement if he invented it in 1956 and had the patent for 14 yrs?

edit: grammar.

He was stationed overseas in Germany in the 60s and likely did not have the time to continue the efforts

This reminds of of Larry David and the Cobb salad.

Was that the one where Larry got a sandwich named after him at his favorite restaurant but he didn't like it?

12 points · 6 months ago

No, that was when a guy whose last name was Cobb got offended when Larry wanted to change his Cobb salad order because he claimed that his grandfather invented the salad. Larry later calls him out by saying that the salad was named by Bob Cobb, and the guy claims that Bob stole the idea from his grandfather.

But to be fair, all punches landed on a blind guy are going to be sucker punches, deserved or not. But good on him for calling him out.

So what? Having a sense disability doesn’t suddenly mean you’re excusable to scrutiny and can get credit where it’s not deserved etc

but he's so brave

The problem is using cruise control becomes a real pain in the ass because you have to deal with these drives in front of you. It becomes a fine art of making sure you get out into the other lane before getting to close and another car is overtaking you. You're then having to constantly having to go in and out of CC

You can speed up in CC and then just let off the gas and CC will resume back at your set speed.

This reminds me of a time in the late 1980's or early 1990's when I worked as a bartender. It was a small local tavern in Naperville, IL adjacent to the town's railroad station. It was a slow weekday night. A few several and a group of four young ladies, all sitting at the bar. The ladies were talking and laughing; they were having a good time. A couple of the regulars were playing the juke box. Due to the sound level of the of the ladies merriment, the fellas couldn't hear the music. They asked to turn it up, which of course made the girls talk louder. This happened a few times. The music was pretty loud as was the gals conversation. I said to the guys, "I can control the sound level of those girls with this knob." I turned the music down slowly and as I turned it down the conversation gradually muted. As I turned it up they became louder. I even turned it completely off and the conversation stopped completely. It was a fun little experiment in human behavior. I'm not sure that this is the right place to post this story.

TLDR: At one time in my past I could control human voices with a volume control knob.

NSFWTLDR: His knob left women speechless.

And I always thought it was just invented by a lazy person. Garfield the cat lied to me.

Somehow I picture every scene driving with the lawyer to have Seinfeld music going, while the engineer grits his teeth and then complains to his apartment neighbors later.

I'm confused, would he speed up as he got to the juicy part of his story, and slow down when he was giving exposition? How does speech affect someone's driving speed, is it just a lawyer thing?

Probably would slow down when he was focused on talking about something and then hit the gas again after he made his point and then repeat.

For decades I’ve been using cruise control perhaps 85% of the time. I’m always aware of my speed as well as everyone else’s speed. Most cars on the road have that feature and if everyone figured out how to use it AND respect passing lanes driving would be a pleasurable experience. In addition to sensors which detect distance autonomous vehicles rely heavily on cruise control too.

I do long distance driving a lot. It drives me insane watching people vary between 80km/h and 140km/h in 110 zones the moment an overtaking lane appears. I want a sign on my car that says "I use cruise control, you're the douche bag" or something wittier...

I had a friend who did this. His idea of going 70mph was averaging 70mph. So, he’d accelerate to 75 then take his foot off the gas till he was going around 65 then back to accelerating... I murdered him and disposed of his body in a 55 gallon drum. It feels good to get that off my chest.

My wife tells me that I tend to do this if I am talking while driving. Doesn't matter if it is to someone in the car or on the phone. In my case, it is a fluttering of the gas petal in a gentle motion. Now I go out of my way not to do it.
