In order for everyone to just freaking go, their cars would have to be attached somehow.

I wonder if anyone’s ever thought of linking a bunch of cars together so they can all stop and go simultaneously. And hey, since the cars are attached and all need to go to the same place, we can build a track instead of using high maintenance rubber on pavement and-

oop, we invented trains

What I dont fucking get is that even in Europe where even in shitty countries like Hungary and Slovakia we have train tracks that’s about thousandfold what the US has, and we still put shit on Semis and have them drive between cities, cities that are all fucking connected by train.

Why aren’t we fucking putting everything on goddamn fucking trains, and then do only the last miles of the delivery on trucks, they could even be electric as that would eliminate all the drawbacks of electric semis, having them only go short distances

AFAIK a big reason for this is because we’re utterly anal about making everyone pay for railways, while roads are obviously necessary for civilization to exist and thus they’re perfectly free to use!

it’s the same corrupt double standard that applies to public transport, it’s just a systemic “oppression” of efficient systems in favour of inefficient ones that let money be funneled into the pockets of asphalt manufacturers and car companies and whatnot.

And instead of each one having a small engine, we could combine it all into a big one more efficient than separate ones would be!

Some sort of linked car-train lane that your car could use self-driving software to enter and leave would be an interesting concept. Like HOV but everyone is linked at the same speed.

This is trains but worse. The HOV lane also does not do much for traffic. It’s slightly less miserable to sit through a traffic jam at times, but often is similar speed wise to a regular lane.

There is nothing more American than being in traffic. You’re never more in touch with a systemic failure, yet we blame it on the choices of individual drivers, all the while unaware that we’re part of the problem.

It’s a little of column a and a little of column b. When I’m driving and some absolute piece of garbage is riding directly next to the car to their right, I equate them to a blood clot, which is funny, because they also make me feel like having an aneurysm. I also don’t forgive the driver on the right, because they are more than capable of allowing a space for other drivers to pass.

The absolute lack of awareness on the road is startling. I swear to God, people are looking through straws and their neck doesn’t move.

Building extra lanes, though, does not solve the problem.

Traffic dynamics are really interesting. Even after you clear the obstruction, the traffic jam remains and becomes a “ghost jam” that propagates backwards down the road until it eventually fizzles out.

Just ONE car can reduce traffic jams. Try it: leave enough buffer such that when the car in front of you stops, you almost reach their bumper at like 5 MPH but never stop b/c it’s time for them to move again. The guy behind you may never actually stop too.

So you had all these stoppers in front of you, and several cars not stopping behind you.

Enough people do this, and there’s no more stop & go. Just cruise 5mph the whole time (not 10, 0, 10, 0, 10, 0, which sucks).

Not sure what the problem is. Keep doing it.

This is how I operate in most traffic jams, since I only own manual cars & it’s much easier on my leg.

I genuinely don’t even remember any specific scenarios where somebody merging in caused me to have to come to a full stop (where I wouldn’t have had to stop if they didn’t merge). Not saying it never happened, but it was so rare and unnotable that I don’t remember.

I do live in the northeast US, so maybe that has something to do with it, but I don’t usually feel like I spend meaningfully more time in traffic because I let a few people in front of me.

Bonus benefit: my life is measurably better since I stopped getting pissed about people being in front of me. Road rage had such a broad impact on me, even after I got out of the car.

The world would instantly be a better place if all the mouth-breathers in it could figure this out simultaneously. Wow, you’re pissed off at someone being “in front” of you. That’s because there’s totally an Earth-shakingly significant difference between having 9,784,326 cars in front of you vs. 9,784,325.

Honest answer involves deep breaths (at least as one first adopts the method), chuckling at one’s favorite podcast, and recreating the buffer.

On certain roads, monkey see monkey do and eventually folks behind you kinda copy you and there’s a chance fewer and fewer folks will be cutting you off. Notice this most on the longest trips. Perhaps they’re not copying you, btw, rather the most aggressive drivers continually pass you until a small cohort of Big Spacers remain behind you. If some of these Space-Not-Racers are in front and around you too, aggressive drivers passing are passing without cutting you off as much - they have enough space to jam themselves into the bumper of the car in front of you.

Kinda funny going around a curve and seeing a hundred cars bumper to bumper ahead, then checking mirrors to see safe following distances :) (oh yeah this style is safer too not just more efficient!)


Can require some SERIOUS brain hacking. How mad would we be if someone cut in front of us at the grocery store? We’d go butts2nuts in a blink. Gotta just, like, flowww mannnn

If I leave any kind of gap between me and the car in front, it is an inevitability that some jackass will swoop in to cut me off. Happened 7 or 8 times just yesterday. Texas drivers are a menace

Yeah when I do that then every time there’s a gap another person comes to cut me off, so it ends up with me pretty much at a dead stop while people go in front of me over and over. People underestimate just how many asshole drivers there are around here lol

I concur. I used to be able to leave a huge gap and nobody would care. I drove a manual and didn’t want the hassle of stopping. But, I tried this recently, and I ended up making the fast lane the slow lane and I had the guy behind me honking and yelling out his window to stop letting everyone in.

Piss off the wrong guy in Texas and see where that gets you. I was lucky all he did was honk and yell.

I learned this technique – we called it “cutting off the head of the snake”.

Traffic moves like water, and becoming fluid and just rolling sometimes can kill traffic completely, I was on a stretch of bright red (5-10 mph) that began moving at 55 MPH after patiently rolling – there was no actual reason for the traffic jam.

Driving stick, I would do this all the time. In fact, I’d do it in the left lane, which I would never do, but for the fact all of the lanes are just constant stop and go. I’d leave massive buffers, 20-30 cars, and just cruise 5-10mph, and never stop. I just don’t understand why anyone wants to use their brakes at all, I hate using my brakes. I’d rather just coast in perpetuity than feel inertia in any direction.

From above the whole thing looks like an accordion. Drivers who tailgate tend to overreact when they see brake lights 50 feet in front of them, compound this by the guy tailgating them and so on. Leave a buffer to absorb this and it smooths out

All it takes is one guy behind you checking his phone, getting distracted so he gets cut up to create another stop start system about 5 cars back.

people who insist on going full speed and then SLAMMING their brakes drive me to drink, and this applies to literally all modes of transport.

If you’re walking through a grocery store and are about to round a corner, fucking slow down so you have time to see anyone else coming your way, then you can speed up again when you know the coast is clear.

If you’re driving a car and coming up to a red light, or even worse a pedestrian on a crossing, FUCKING SLOW DOWN and just coast slowly, it’s not worth the off chance that you get to blast through at full speed, not for you or anyone else.
