you could do a distance test.

have the cars start behind the line, take off and when the radar gun hits 100 or 60 have a flag man drop the flag and the guy hits the brakes. use a lazer range finder to bounce off a sign on a stick held either at the front or back of the car.

if you wanted to award points take the distance and subtract from whatever distance and award those points.

not a timed thing but could be another event.

you could do the same thing with a stop watch. flag man to start the car and watch, flagman to signal whatever mph, then someone with good eye to stop the watch.

sounds like a lot work for a little payback.
