Theoretically, if there's not enough visual information for AI drivers, then there's not enough visual information for human drivers, and that's a problem with the road. (Which, to be sure, occasionally there are roads like this: e.g. merging onto a higher-speed thoroughfare from a lower level, with a very short distance between "where you're in a position to see the merging traffic (and not that much of it)" and "where the roads have fully merged (and there's no shoulder)".)

This Mark Rober video has been debunked several times:

That is not a debunking... That's someone running a similar experiment and getting a different result. That would debunk the claim that Teslas can never detect a painted wall. It does not debunk the claim that Teslas will sometimes fail to detect a painted wall.

And in a safety-critical system, the distinction is not mere pedantry.

I mean he didn't even use FSD.
