Good suggestion to fix the problem we have, but I don't think a vote pause is the best option. Flopster also mentioned a flaw, I think this needs resolving.
Example:
DoubleYou : 11 second race, 90 second countdown till next race
LeMans-GT : 600 second race, 90 second countdown till next race
Obviously with DoubleYou there would be no need for more than 10-15 seconds countdown for the next race, but LeMans-GT is 600 seconds, so maybe more than 90 seconds is needed for the other racers to finish.
I'd rather calculate an extended auto-countdown on 1st finisher. I'll look into it.
