Terry,
I agree and even if the held them to the exact limit they would still get tickets as they would still push it just as far as they can. And with the computers and timing rings, they aren't going to get away with anything. I wonder how many people lost very close races back when they had to use a camera and people to try and tell who got to the finish line first. It is hard to believe that any person had good enough vision to determine between cars that finish a few thousands of a second apart.
