Don't people get thrown off of tracks for running faster that they are teched for? None of them get thrown off-during this very specific event. If it were really about safety regs the first pass below the min ET or above the MPH the competitor would be shown the door until they could pass tech.
As was previously mentioned, You go through "tech" at check in, then show up at tracks and race. I suppose the assumption is that because you cannot hand in a faster slip, then you won't run faster. That being said, the tech inspector last year asked if I was going for 10.0 (even though I am in the "no bar" crowd)
If every track had to tech and police 400 cars, all rolling in at different times, the event could never happen.
Faster, Faster until the thrill of speed overcomes the fear of death...
