If drivers got the same training and stuck to the same rules as airline pilots, we'd have a lot less accidents. Most accidents [citation needed] are still caused by reckless driving; inattentiveness (exacerbated by driving assistance), speeding, drunk driving, aggressive driving, etc.

Moving to automatic driving will probably be a thing long term, but for the short term, it's a human problem. If only people were held more accountable for driving badly.
