I don’t know how we could say humans are “good” or “bad” drivers. What are we comparing against? We’re the only thing that drives cars (other than a few self driving cars).
If someone had said said “trains are safer than cars” I’d agree with that comparison, but the question is are humans good at driving cars. I don’t know if we’re particularly better at driving cars than trains, trains are just better designs.
I mean, you wouldn’t say humans are good at tic-tac-toe, and bad at chess, right? Chess is just a much harder game.
