The SCCA 'cone racers' started getting really pissed off when a few 'drifters' started attending the events and mysteriously 'got sideways' a number of times.
Now they make a BIG point of 'no drifting' at the events (bunch of spoil sports if you ask me).
Do the autocross, and if the spirit moves you, let it all hang out.
Fart in the library? Now THAT was funny!
