I'm a total noobie when it comes to track/racing so I hope this hasnt been answered or is just common sense once you actually start attending the events. My paranoia has me thinking that doing a ride share to the track/races is the smart thing to do in case a bad enough crash has you unable to drive home, plus the bonus of having someone around to help setup/tear down, hang out with, sponge ideas from, share costs and equipment, etc.
