My fear is similar, but more along the lines of adversarial attacks as various weaknesses are exposed. Imagine people taking advantage of zero-day exploits that cause self driving cars to veer off the road, stop suddenly, collide, etc. It is really not that far fetched. This technology is very far away from maturity, IMO.

Or even without an occupant?
