I recall getting tagged once during a free practice session prior to a Polo Cup race. I left the guy enough room to make a safe pass and he chose to take my driver’s side mirror as a mememto. I was really cheesed off at the time as I didn’t think there is any reason for contact during an free practice session.
Just as well I’ve not tried my hand at NASCAR. While practicing for an upcoming event several cars got into a tangle. The end results was Parker Kligerman sent riding the wall skateboard-style, while other cars were sent in every other direction. Thankfully no one was hurt in the accident.
