This is pretty important. The way the guys does this is very close to how you could also fool a human by hanging up real stop signs in the wrong places, and "stupidity" people would start to respect them.

The only difference here is that a mere 500 ms flash elicites a response, where a human wouldn't notice. on balance, a 500 ms response time does seem like a feature more than a bug compared to a human.

Well, which one is it now:

Are self-driving computers superior to humans and make less mistakes, or is it OK for a computer to be tricked by something some humans would also not detect?

Btw. I think I can tell if there is a real stop-sign or something on a billboard after some 'huh'-moment and without slamming on the brakes. And humans still go circles around AI regarding plausibility-checking very out-of-the-ordinary events.

It's neither.

Self-driving cars aren't superior.

There is 1 death in 100 million miles driven on roads; self-driving cars are currently operating around 1 death per million.

Personally, I do not expect self-driving cars this century to get anywhere near human safety levels (assuming cities/etc. remain as-is).

You want to drop some links to back up your claims?

I haven't read it all -- my numbers come from another paper, I can't recall. But it's talking in the right ballparks.

It isn’t either/or. One system can be overall superior another and that system can have different vulnerabilities and weaknesses. Cars are generally considered better than horses for transport, but cars also cannot use grass for fuel.
I suspect flashing a stop sign sized image of a stop sign for 500ms on a tv mounted where the stop sign goes, at an intersection that should probably have a stop sign, would get most people to stop.
I thought the same thing and most certainly slow way the heck down while trying to figure out what the heck I just saw. I'd probably presume it was some sort of programmable temporary signage on the fritz and treat it like a traffic light with the lights out.
