I've made wrong turns on course before as a race vehicle driver, ironically on something like the 7th lap (i.e. should have known better) after they moved some fencing (it's their fault!!) and opened a side street a block early. Fortunately no riders in trace!!!
It is very understandable and happens more than it should. OTOH it is entirely unforgiveable and cannot be tolerated. String them up! No, really. I suspect that pilot will be blackballed for a while and will have to work their way back up through the ranks.
