It happened to me many years ago after leaving the Flats. I was in a '96 Impala SS and if anyone knows that car it has insanely wide tires and a horrible front end that is impossible to align. The nature of the beast would cause it to tramline like crazy. Apparently someone noticed me doing this and thought I was drunk (I wasn't). I got pulled over on 611 and was given a field sobriety test....which I passed. So, I don't know if it's illegal or not (I doubt it), but they are gonna pull you over regardless.
