Never said it was a race, but the point is, if someone goes off the track or spins, they instantly lose 10-0, so waiting for the other driver is pointless. If you want to do it, that's fine, but it shouldn't be an enforced rule. I, as a judge, always require drivers to complete the course, otherwise it makes judging very difficult. If one driver crashes or spins, the other driver should still show that he can continue through the course without breaking drift.
On the topic of people asking about what new track to use, are you not sticking to one track for the entire round up until the winner is decided, then move onto a new track for the next new competition? Drift comps don't switch track halfway through, you run until you have a winner, then you go to the next round at a different venue. Or have I mis-read it?
