Well? Do you? I've been looking for a nearby trackday event meself...and it'll be awhile before I can get my car prepared for such an event, but I wonder how many people go to HPDEs, Trackdays, run oval tracks, drag race, et cetera, in real life.
and, no. Don't try to prove your cojones by racing morons on the street. I can't guarantee that your bragging (particularly if there's video evidence) won't make it into the hands of the police, and I don't want anyone to get into trouble, anyway. Seriously...it's better if you keep that activity to yourself. Deny, deny, deny.
