  Yeah, in theory it’s great but every time I try it people just cut in front of me then slam in brakes causing me to have to brake then adjust then repeat ad nauseam. People suck.

    Yeah, maybe I’m fooling myself but it really seems like hanging back more makes me have to do more sudden braking. Traffic seems smoothest when I’m close enough to discourage cut-ins …. Even if that means Im more at the mercy of traffic in front flowing down a bit

    You need to give even more space then so that them doing that doesnt make you slow down. People cutting in front of you also helps because those are the assholes causing the brake waves.

      I have adaptive cruise with a settable car length and increasing the gap length just makes the cars behind you act more deranged.

      I’ve found the only setting that doesn’t make everyone around me fly off the handle is the lowest (one car gap) setting.

      I also drive in the diamond lane on long trips and typically have my upper speed limit set well above what the person in front of me is driving.

        This is actually an argument for why these features should be mandatory. Traffic is caused by humans and their silly emotions. These types of self driving features with inter-communication would erase traffic jams.

      At that point, you’re the guy doing 15 mph under the limit in the left lane.

      Please only attempt this in the right lane.

        Everyone is doing 15+ under. We’re taking stop and go traffic. What are you talking about?

    This is why I thought that maybe it would be good to have some kind of pacing cars, e.g. operated by traffic police? I.e. when you already know or can anticipate that there is a large jam building up, you bring in one pacing car on every lane at an appropriate low speed and everyone has to adjust, so the thing you mentioned won’t happen.

      Or we could just build trains and other alternatives to cars, which would end up cheaper, faster, safer, environmentally friendly, …but we have big oil.

      Nah, cops being on the highway is one of the big causes of traffic. Everyone slows down to the speed limit when they come up on a cop and many are too timid to pass at all. This causes a huge brake wave and fucks everything up. It’s why I don’t think speed limits should even be a thing or should at least be adjusted because most highways are so low that just about everyone ignores them (and is not harmed doing so) until law enforcement appears. If people want to go slower that’s fine but they need to keep right when they aren’t passing and everyone needs to leave plenty of space in front of them so that traffic is permeable enough that people can get to their exit without causing brake waves and absorb the “shock” when it is necessary for someone to hit their brakes.

      I feel like regular patrol cars might work like this already - who’s going to blow past a cop driving down the road?

        me, because i know what speed they’ll pull me over at and if they’re doing 20 under that, who cares

    Then leave another gap. There are finite idiots in the world, and you cannot actually go backwards.

    Works for me even with cut ins, gets easier with practice I’d say! Couple interesting YouTube videos on it, one here:

  Adaptive cruise control FTW. Matches speed with the person ahead of me (up to the max that I set) and maintains a gap that I can specify. It starts slowing down long before I’d notice the gap closing if I were doing it myself, so the +/- acceleration is a lot smoother as a result.

  source

  • kryptonianCodeMonkey@lemmy.world ⁨22⁩ ⁨hours⁩ ago

    So, I don’t know exactly how the adaptive cruise control works. But if it is slowing down and speeding up to maintain a specific distance, that does not fix things. The idea is to maintain a specific speed such that, as the people in front of you accelerate and brake, speed up and slow down, you have enough distance to not have to do that. You should essentially match their average speed with enough gap that their braking doesn’t put them close enough to your bumper that you have to slow down yourself. Normal cruise control would be better (except mine won’t set at speeds under, I think, 20mph) because your speed wont change. Adaptive cruise would make your drive safer, maybe, keeping you from being too close or failing to react to the change in traffic speeds, but I dont think it would solve the traffic issue itself.

    • Omgpwnies@lemmy.world ⁨19⁩ ⁨hours⁩ ago

      It’s not “locked” to a specific distance, it’s fairly elastic and the exact follow distance varies based on speed. So, if traffic slows down, it will gradually close the gap while also slowing down. The end result then is far less drastic speed changes.

    • aesthelete@lemmy.world ⁨20⁩ ⁨hours⁩ ago

      You aren’t solving traffic as an individual driver anyway. Sorry to burst everyone’s atomized bubble here but that’s complete nonsense.

      If you manually maintain a large gap in front of you, everyone behind you becomes complete weirdos.

      We could “solve traffic” by not requiring single occupant car drives to accomplish everything in our daily lives.

  Californians te the worst drivers in the world because none of them understand this simple concept. Every day I’m driving, I give more than enough space in front of me for someone to cut me off and I don’t have to brake. It’s simple. However, I’m constantly getting people riding my ass. Switching around me. And being over all menaces just because I’m leaving a roper gap between myself and the car in front of me. It’s wild.

  Right, if you think about the creation of traffic as a negative speed wave which causes compression, and traffic alleviation as a positive speed wave which requires rarefaction, then it becomes clear why traffic is so stubborn. When people are so bunched together, no positive speed wave can propagate. Which is why you literally get to to the point where the original idiot slammed on the brakes and the traffic magically disintegrates. If everyone stayed 5 car lengths apart in traffic, that alleviation would actually propagate backwards as fast as the initial congestion.
