Actually I’d think handling unclear situations like this would be one of the major things that makes autonomous driving systems so complicated and challenging to develop.

You are completely correct. The “happy path” or what to do if everything goes right is fairly straightforward for autonomous cars. It’s when it gets into exceptions or unexpected scenarios like this that it becomes a problem. It’s a car so you can’t just stop it in the middle of the road, but you cant tell it to ignore road signs either

I knew printing your own signs would lead to interesting exploits, but this is just next level.

Putting it into reverse requires you to stop first.

i think you could theoretically drift to maintain velocity in a different axis while accelerating in reverse to technically not ever “stop”

How would that work?

I’d just drive off the road to the right. Where I’m going, I don’t need rules. I may need new tires, though…

And suspension, shocks, axel, exhaust, undercarriage…

You could reverse down the road, or would there be a moment between forwards and backwards when you’re stopped?

It’s not a u-turn if you skid into a wicked 540

You have to cross over 0 at some point

Stopping isn’t the same as driving at 0 speed.

A car is stopped if and only if its acceleration is also 0.

And velocity is 0. Otherwise Johnny 100kmph is technically stopped
