Good luck in NASA Geezer. (I'm sure you'll never be tagged in a NASA race - sure.)
Have you considered vintage racing- the one's that only allow passing on the straight?

And I guess I can still tell the difference between someone scratching and someone waving.

Agree or disagree, if you had been my student and had taken your hand off the wheel to scratch your chin in a yellow flag situation instead of maintaining control of your car, I would have flunked you when I instructed for NASA.
