To be fair, humans are fairly poor drivers and generally can't be trusted to drive millions of miles safely.
Actually humans are fairly good drivers. The average US driver goes almost 2 million miles between causing injury collisions. Take the drunks and drug users out and the numbers for humans look even better.
