Driving is dangerous and many drivers suck at it. But if you want a relevant comparison only consider similar circumstances and driving conditions (motorway or city traffic? blizzard or sunny?). Then normalize for the number of vehicles of each type and their age/capability (20 year old clunkers with failing brakes aside). And in the end count in the times AP made a mistake and the driver corrected it (Tesla has the info, only they know why they refuse to make it public).
