I’ll start. Stopping distance.

My commute is 95 miles one way to work, so I see a lot of the highway, in the rural part of the US. This means traveling at 70+ mph (112km/h) for almost the entirety of the drive. The amount of other drivers on the road who follow behind someone else with less than a car’s length in front of them because they want to go 20+ over the speed limit is ridiculous. The only time you ever follow someone that close is if you have complete and absolute trust in them, and also understand that it may not even be enough.

For a daily drive, you likely need 2-3 car lengths between you at minimum depending on your speed to accurately avoid hitting the brakes. This doesn’t even take into account the lack of understanding of engine braking…

What concepts do you all think of when it comes to driving that you feel are not well understood by the public at large?

State specific, but in mine, left turns on red are ok onto one-ways/freeway onramps.

I have replaced a car lengths or seconds guidance with looking as far as I can ahead to predict what the cars near me will be doing on the next 30 seconds or so. If I see brake lights half a mile ahead, that means the car inb front of me will probably be slowing down in about 30 seconds. So I take my foot off the accelerator and cover (but don't press) my brake pedal.

Traffic on the interstate it really pretty predictable IF you spend a significant amount of time looking far ahead instead of only at the far in front of you. Obviously keep watching the car on front of you, but not ONLY that.

This is a good practice in addition to not tailgating, but it falls apart in cases where you're behind an ugly SUV that blocks your view of what's ahead :(

For car distance I've seen 2-3 seconds start to be recommended, since people are not good at judging distance. So counting how long it takes to reach the same fixed point as the car ahead.

Zipper lanes.

Each person goes one after another in an orderly fashion because it gets people moving faster, but instead you get asshats that either are trying to bully people by not letting them into their lane or trying to sneak in with the person coming into the lane because gee whiz, there’s a small opening!

It makes me so mad to see people not know how a zipper lane works, literally the easiest shit in the world.

Yield sign. It means stop if there are cars, pretty simple concept.

The risk undertaken to make a short trip at 20mph over the speed limit isn't worth the few minutes it might save. On paper it seems like it would save a lot but the reality of inevitable stop lights and traffic cause different results.

Passing doesn't save much time when the city you're in has a ton of long red lights, There's a highway I travel daily, rather short 12 mile lap. People will absoluty blast past me going 20-30 above the speed limit, and then 10 minutes later they will be right infront of me at a red light. There's no point in making your ride so much more dangerous just to shave a few seconds off your time.

I also have people pass me, merge back in, and then brake hard to turn off pretty fucking often on this commute. It's insane what people will do.

Your car 100% definitely has automatic headlights, so why the fuck are your headlights off in the middle of the night??

[–] NotSoCoolWhip@lemmy.world 4 points 2 years ago

No? There are still plenty of vehicles without automatic lights. I own 4 cars and none of them have auto lights.

[–] ZC3rr0r@lemmy.ca 3 points 2 years ago

This annoys me too, but I find that lots of shops turn off the headlight's automatic mode when brought in for service. This leaves hapless drivers unaware of the fact that they are driving around with just their DRLs on until they either get a ticket, complain about it to the dealer, or figure it out on their own.

Following distance should be 1 car length for every 10mph you are travelling. 70 mph would mean 7 car lengths.

Is 95 miles (~150km) one way considered normal in the US? I live in Bangalore, India and my commute is barely 20km (takes me 45mins - 1hour) which is too much for me.

Me and most people I know would rather shift than travel 150kms a day. Can’t imagine the toll it would take on me, my fuel budget and my car
