Edge cases in this scare the hell out of me. I'm envisioning watching CCTV of every Tesla that follows a specific route on a specific day merrily driving off the same cliff until it's noticed.

I mean what would have happened here if another Tesla or two were directly behind Huang, following his car's lead?!

Possibly nothing, I'd assume the stopping distance would be observed and the following cars would be able to stop/avoid, but I wouldn't like to bet either way. Perhaps, in some conditions, the sudden impact on the lead car would cause the second car to lose track of the rear end of the first? Would it then accelerate into it?

The report indicates the system ignores stationary objects. I would not be surprised if a suddenly decelerated car in front of the system effectively vanished from the car's situational awareness. Your scenario does not seem that far-fetched.

An attentive human would realize something horrible had happened and perhaps reacted accordingly. A disengaged or otherwise distracted one may not have the reaction time necessary to stop the system from plowing right into the situation to make it worse.
