Tesla owners warned of 'full self-driving' risks even before fatal crash

Tesla's "full self-driving" feature has attempted to drive under a railroad crossing arm while a speeding train passes. It's nearly driven head on into a concrete wall of a parking garage, attempted ill-advised left turns, clipped at least one curb, and at least one driver was able to set a maximum speed of 90 mph on a street where the posted speed limit was 35 mph, according to videos posted on social media.
