Edit: please disregard. I didn't read carefully enough. Obviously it's not dangerous to fall asleep when someone else is driving.

Describing this as "he gets in a car and it starts driving" seems like a pretty intentional decision; I suspect that either the brother doesn't drive, or this only happens when someone else is driving.
