I know that my sample size is comically small, but in my experience, the scariest drivers I've ridden with as a passenger - out of the experienced drivers, who have been behind the wheel for decades, and excluding people who just got their licence - have been full-time professional artists. Like I have ridden shotgun with exactly two fully grown adults who were memorable to me as being "holy shit!" experiences, and one of them was a sculptor and the other one was an opera singer. Neither one actually hit anyone or anything, but the sheer amount of close brushes they had and casually breezed through was more than any other car ride I've ever been on, combined.
The fact that I am now a full-time professional artist, and also the worst driver I know, supports my theory. I don't drive unless there's nobody else who possibly can, and I tell people that I can't drive - I have a licence, but that doesn't mean I can drive. I am merely legally allowed to do that.
