I'd say this also kind of shows weakness of neural net based driving - it's difficult to enforce "corner case behavior". I.e. If car ahead of you moves out of the way and "noise" cloud moving very quickly towards you appears on radar, there is something fishy - do something (i.e. the same as the car ahead of you). I know there can be false positives, but RELIABLE obstacle avoidance is necessary before even thinking about FSD. At least we did it that way in our (model scale) robotic projects.
