I just starting playing with "the dark side" this past winter, and
I'm not having to fight anything more than boredom on the
superspeedways when there aren't enough cars/trucks to make traffic
interesting. So I certainly don't have 5-year's worth of practice in
NASCAR.
It *is* a different style of driving. But I can't see where anyone
who was respectable at one wouldn't be respectable at the other.
(Well, maybe someone used to speedways wouldn't do quite as well on a
road course in a GPL car... but you're going the other way.)
