I agree with the transponder thing. Was at Tri City last night, and what a great show. They use transponders and it takes all the guess work out of where cars were when a yellow comes out. They dont use a cone for restarts, but if they did transponders would take judgement calls out of the hands of flagmen. Flagmen cant see everything, all the time, this would definately help. Cant imagine what the cost would be though.
