Among what others have stated, I guess it depends upon what you mean by "safe". It's possible that Tesla autopilot avoids fender benders but increases chances of fatal crashes.

If you're looking at deaths, in the USA, there's about 1.5 every 100 million miles driven (this includes pedestrians/etc). That's a pretty high bar. Way higher than most autopilot apologists imply.

I'm not saying autopilot won't ever be safer than humans. Just that it isn't as easy as it appears.
