His evidence is the 4 driver fatalities resulting from Tesla's Autopilot, which is infinitely more than the 0 driver fatalities of any other self-driving system.
Including pedestrian, cyclist, and other-vehicle fatalities, Tesla's fatality statistics are so bad that they exceed the combined total of every other self-driving system back to their respective launch dates.
Where did that 4th fatality come from? I have only ever seen reports of 3.
Either way, you can't credibly use aggregate totals without at least mentioning the underlying rate statistics. That would be like me saying that over a 100 people die every day from manual driving but only 3 people have ever been killed by self driving Teslas and therefore Teslas are safer. Statistics doesn't work like that. Tesla's have more fatalities than any other semi-autonomous car because they have orders of magnitude more miles driven. It is far to early to tell whether they are either safer or more dangerous.
