Its principles also hold up for drivers in China. Guess the chinese love copying american things right down to driving just as badly :-D

Anyway, jokes aside, this has a lot more uses than proof we are all bad drivers. I can this being a great simple way to show queues in a factory/shop/office coffee machine . Awesome work and i wish i as 5% as good at coding to be able to do this when on holiday. On my hols i would be lucky to get past hello world. Kudos to this guy.

It'd be interesting to implement lane discipline and see how one bad driver effects the rest.

Yes, please! I suspect lack of lane discipline to be the single biggest disadvantage US freeways have to American's. I would love to test that at least via simulation. I would expect that two lanes with lane discipline are better than three without. Potentially even better than four.

Some bugs (cars not always breaking when another is standing still ahead; cars crashing at the beginning if you hit launch too quickly), but overall a fun toy to play with. I would like to know what realistic values are though: I know that 200ms reaction time is a good case, but what are actual average cases? It should be set to that by default. Or acceleration speed, is 5km/h realistic? 10? When set to 5, I cannot s…

I think the braking is a feature not a bug. See the "reaction time" I'd assume that means that some just aren't reacting in time to not hit the car ahead.

That might be, I don't know when they would have started to break but they were extremely late if ever. But perhaps it was well within the reaction time I set (350ms), for me it's easy to think they just kept driving because I saw them coming from afar.

Lots of cars do 15 km/h/s (that's a 0-60 mph time of ~6 seconds).

A basic Honda Civic will be around 9 or 10 seconds, which is roughly 10 km/h/s.

5 km/h/s would feel pretty sluggish.
