What about this current incident? In your opinion?

Barring a time machine, we've very little way to know when it comes to one specific incident. Again, people distracted by their cell phones kill people on a very regular basis in vehicles without autopilot.

If we had better aggregate stats we could compute the statistical likelihood of it, but this stuff isn't tracked anywhere near as closely or completely as, say, aircraft accidents. I don't trust Tesla's self-reported cherry-picked stats.

People glance at diatractions, aware that they are responsible for driving their car. Believing that your car can drive itself is something new.
