I could see that possibly being true. I mean, driving is kind of weird; it seems to be mostly done with a part of the brain that can operate automatically with little conscious effort. It's sort of like playing the piano: if I'm playing some piece that I know well I probably won't screw up unless I actually try to consciously think about what I'm doing, which is when things fall apart.

That said, I think people should be reasonably safety-conscious about vehicle maintenance, avoiding risky situations, and avoiding things that could sabotage the automatic-driving part of their brain, like doing other things at the same time that require their attention and their hands and eyes.
