I saw an article about an idea to put self-driving cars on the road which can drive a tiny bit slower than other cars around them, gradually allowing a large gap of antitraffic to form in front of them, which can contract to destroy a traffic jam wave.
And I was like dude I've been doing that for 10 years and I'm not an AI. You don't need an AI, you need one person in a thousand to have read Bill Beatty's traffic wave theories.

To make a traffic jam without an instigating event, you need thousands of drivers driving like jerks, tailgating and being aggressive with throttle and brake. This happens every day in Pittsburgh. Unmaking a traffic jam only takes two or three good drivers.

@ifixcoinops I read in a British advanced driving guide that if there are 4 cars ahead to leave a bigger gap rather than follow close behind which I do at busy places like the approach to the spiral roundabout here that goes to the A12/A14 (this works well, and avoids surprises and near misses when someone realises they are in wrong lane to get to Essex/London)

@vfrmedia A thing they do in England that they don't do here is the adaptive motorway speed limits, which I saw acting in what seemed like arbitrary ways, but which were probably sensing traffic flow and creating a smooth slowdown to 40 or 50 in order to dissipate a forming jam a few miles up the road.

(another thing America needs to do is enforce speed limits for white drivers)

((I never thought I'd say this, but I actually miss speed cameras))

@ifixcoinops I encountered these when driving to Reading to visit relatives who still live there - sometimes it looks like the limits are changing like a fruit machine but if you keep your wits about you it isn't too bad (and there is a minutes grace period during the changeover)

@ifixcoinops

I've often thought hiring people to drive slowly down specific stretches of highway in places jams are frequent in order to prevent them might be possible; the models I saw once required only 1 in 20 drivers to not be aggressive asshats to prevent clogs.

I cannot honestly imagine what to call that job, because WTF? "Traffic Prevention Agent"? It sounds like a bot generated nonsense title.

@ifixcoinops People in the city drive Very aggressively and they are not polite to each other. That's the problem down there.
If you are polite and try to take turns or let people in like a fellow human being they honk and yell at you.
Eff that noise. I'll stay up here.

@ND3JR That whole situation on the downtown side of the Squirrel Hill tunnel needs to be dynamited to powder and the designer brought to justice.

@ifixcoinops oooh this is a really good read, I love this so far

@null Spread it far and wide, mate. If one person in traffic knows how to make antitraffic, and they're good at it, then there's no traffic. :)

@ifixcoinops i’ve already figured this all out for the most part, but it’s really nice seeing it all put into words

@ifixcoinops

That's exactly the same around Paris in France and that's why I hate driving there.
I was taught that driving is cooperating with other drivers. But 90% of those stupid assholes are driving as if it was mandatory to fight other drivers, struggling to put their car at the first place of the herd. They just don't know how to drive.
I'd enjoy the time when driving licenses get controlled every five years and bad drivers get sent to school again.

(sorry for my bad english)

@ifixcoinops I feel like I inadvertently do this just driving at the speed limit in Sydney.
@ifixcoinops Well not one, one in each lane, logjamming across with each other so nobody can pass.

@ifixcoinops Interesting stuff! I am so glad I don't live down there.
And by 'down there' I don't even mean as far south as Seattle as in the link. I think Vancouver is even more congested?
<time passes>
Oh yeah: Seattle is far down the list:

It goes Mexico City, LA, Vancouver, New York...
I think Bogata is the 'winner' for the Americas, poor thing.
