I suggest that some of you might appreciate reading the NTSB investigation into the recent (and fatal) accident between a highly automated car and a tractor/trailer in Florida.
Somewhat apples and oranges - the Tesla system was not designed or intended to be fully autonomous - it was a "Level 2" 'supervisory' system intended to assist the driver, not take his place. That he used it as a fully autonomous system so he could watch a Harry Potter film earned him a Darwin award.
None of the automotive systems currently for sale are capable of fully autonomous operation (aka "Level 5"). The best systems currently for sale are Level 1 or 2 - with some Level 3 currently in Beta test.
Edited to add this link that defines automotive automation:
