Hey Joe, cool new name !!
I like the idea of stop go, or 10 second penalties.
I think you lay out the rules, and expectations of driving standards then penalise when these are not adhered too.
For instance, the take out to gain the place, if the car who took the car in front out does not allow the place to be re-taken then penalise.
I actually think the standard over the past 2 weeks has in fact been the best I have known at the club, but like you say accidents can and will happen.
