How many of you would say: "Technology is so advanced, etc. etc. that I'm sure there can be created robots that can do all sorts of invasive surgery?"
Most (if not all) people want a human to do invasive surgery because a human can react to a human body and organs moving around and pulsating during surgery more "responsively" than a machine can.
Even with that, doctors have messed up in surgery (see Dr. Dean Lorich who supposed messed up football player Michael Cox and was driven to suicide due to the consequences of that situation - Michael Cox sued him for supposedly messing up)
So, we trust human doctors over machines for surgery and if a doctor messes up he or she can be sued...
So....
why would society trust machines over humans to "thread the needle" over these "wide to narrow" roads with various type of pedestrian activity alongside these roads....AND THEN....why would society want to make it so these self-driving companies CAN'T BE SUED IF THEY MESS UP? (just like society wants human doctors to do surgery .....yet.....doctors can still be sued if they "mess up")
