Most GPS software is smart enough to not flicker between the highway and the bridge repeatedly though. It's not like this category of problems is a wholly new thing. The car needing to switch lanes twice a second like in one of those videos is fairly unlikely, so if the ML is spitting out that it should, there probably ought to be a layer on top of that that's interpreting the ML output that can take the decision to pick one. Picking the wrong lane is less wrong than being indecisive about it.

I don't know about "most gps software" but I have a Garmin doing that and Google Maps does the same. So in my experience it's 100%. Now if such well established software products didn't figure out such basic stuff, either we're calling it wrongly "basic" (and it's a difficult problem) or the responsible factors just don't bother. The major difference is though, while gps navigation can do with frequent recalculations, realtime obstacle avoidance less so.

It needs to be an input, not just a filter on output. A heuristic that doesn't account for the previously observed state is insufficient because prior existence information changes what gets detected. And it needs to lean heavily toward "if we saw something there before, the safest course of action is to assume that it's still there until strongly indicated otherwise".

It can be a filter on the output and account for previously observed state. E.g. one trivial (and probably pretty bad) solution in that direction would be to boost the probability of small state changes as opposed to large changes.

Normally I'd agree with you, but driving a car is a bit of a special case since in may cases stomping on the brakes is way worse than doing nothing. Take the video of the tesla seeing spurious traffic lights[0] for instance, should it really do an emergency stop in the middle of traffic in that case?

All the machine learning can do is give you probabilities on what the state of the world around the car might be. The software needs to pick from those probabilities some state to act on in such a way to be the least likely to endanger anyone. There isn't a simple correct answer. all the variables need to be weighed. currently teslas seem to ignore some pretty important variables while driving.
