Not self driving but "driver assist" on a rental we had recently would see skid marks on the road and swerve to follow them - every single time. That's going to be a difference between the automated systems and human drivers - humans do some horrifically negligent and terrible things, but... most humans tend not to repeat the same mistake too many times.

With "the algorithm" controlling thousands or millions of vehicles, when somebody finds a hack that causes one to crash, they've got a hack that will cause all similar ones to crash. I doubt we're anywhere near "safe" learn from their mistakes self-recoding on these systems yet, that has the potential for even worse and less predictable outcomes.
