It's a bit of the 90/10 rule at work. 90% of ppl can barely drive while they're driving. I don't doubt a pro/amateur driver can handle multitasking while driving but they're 10%.
I dont doubt a pilot feels like driving is the easiest thing in the world by comparison either. Shit, if ppl got half the training behind the wheel that a single Engine pilot has to take, the roads would be a heck of a lot safer. We'd prob get a bunch of Ernest hemingways behind the wheel.
I think we can agree on two things:
You should have a good reason to take your eyes off the road or just minimize doing it.
Fuck greyhound. It's a bad neighborhood on wheels.
