I have been racing for over 25 years and have seen plenty of crashes in cars that were legal. My NHRA home track is pretty tough when it comes to tech and cars are watched if the car goes quicker than its legal for they are spoken to and are banned from racing that day if they don`t comply/ slow the car down. It becomes a whole legal thing for the track, here in N.J. tracks are regulated by the State Police and they cruise thru the pits on occasion and are called if there is a serious crash , if there is a crash the car is impounded for inspection. Tracks are having a tough enough time surviving they have to protect themselves from liability as their insurance costs are astronomical. I`ll admit that some of the NHRAs rules are nuts and geared toward business for its sponsors but for the most part are for the drivers protection. One time I was at Pittsburgh ( an IHRA track) for a Mopar race and once the inspector saw my NHRA extended tech sticker he said " I know you`re good to go"
