When I used to race on dirt tracks, we at that time (70s) mostly flat towed the race cars to the track.

If a car was badly damaged due to an accident, it certainly can, and does happen. One of the wreckers that the track has at all events would tow a car if it still had one set of wheels that were undamaged back to town after the races. Or someone would load it on a trailer and make a trip into town to get your car home, unload it then drive back to the track and load their own car on the trailer. You never wanted to leave a car at the race track overnight, because it was a known fact, it would be stripped by the following day. Anything of value would be gone if it was left unattended for any length of time.

Loaning of parts was commonplace, and either you removed it at the end of the night, just paid for it, or replaced it with another like part the following night of racing. Great brotherhood at local dirt tracks.
