Poll: who has "official" racing experience?

[MetroMPG]

I've noticed a common theme in GS members: many have mentioned auto racing backgrounds.

It doesn't really surprise me: mastering the art of driving hyper efficiently is similar in many ways to trying to shave seconds off lap times on a track.

Plus some racing background applies directly to FE driving: e.g. taking the widest possible safe line through a turn, to minimize the amount of braking necessary & save momentum.

So, let's see if I can set up a poll that has multiple choice. Check all that apply to your "official" automotive racing experience...
