Only one that isn't true as far as i know is the drivers shutting down before the finish line. They pull the chute before the finishline, and prepare to shut down prior to it, but if they shut down before, how the hell could they win a race? Maybe the pullt he fuel shut off early, but that wouldn't make sense to lean out the engine fully at a full load. There'd be more damage each run then there already is.
BTW..
