Heh, clowncar autocrossing. I had the opportunity to see somebody autocross an old 6-seat sedan (crown vic or caprice?) with all seatbelts in use. It was funny to see all of the passengers heads move in unison.
As far as getting lost, I walk the course at least 5 times. Maybe get a more experienced driver to walk with me.
This was some kind of charity event where you could put a hecker or five (as many as there are seatbelts) in somebody's car for $X/heckler. The driver could pay $X/heckler to kick them out prior to his/her run. The starter's comment cracks me up!
