Drag Strips and Antifreeze

I've been going to race tracks for over 30 years and I've never once heard of a tech guy checking a car for antifreeze. It's frowned upon but heck my local tracks barely check anything in tech. They actually check my seat belt date this year, that's the first in a longtime. I've seen guys with delay boxes in their car at NHRA events with NHRA officials around in classes where they weren't allowed to be. All they do is make them remove them, instead of throwing them out for cheating. Tracks don't really enforce anything as they want as much $$ from the racers as they can get.
