Humans are not perfect drivers. They often do make mistakes, but when it is their mistake they think it was a trivial thing, when it was someone else's they think the other guy is bad. Thus everyone thinks they are a great driver - meanwhile millions of people die in car crashes every year (https://www.who.int/news-room/fact-sheets/detail/road-traffi...). computers have the potential do improve a lot on humans, the only question is will they - I'm optimistic but it remains to be seen.

Tesla claims their autopilot is much better than humans - but unbiased sources that should have data are not talking.
