Kinda getting sick of the green white checkered deal with two, three, or more chances to win.

I think if a race is cautioned on the last lap, It should be the driver who crossed the stripe on the last completed lap as the winner.

For Short track that would mean a 30 lap race was 29. But it would save the pileups etc of multiple green white checkers. For Nascar etc. It would end the race on the last completed lap at the line and not where who was at the time of caution.

ONE SHOT, ONE WIN, Done.

Your mileage may vary.
