And this is from a industry that puts safety as the #1 priority. Having worked in that industry for over 30 years and having experience with SCCA and other sanctioning bodies I think many of the NHRA safety rules are arbitrary window dressing that defy common sense and dumb down tech inspection (no disrespect to the great tech folks). They send hand grenades down the track and make small incremental safety steps and have failed to develop a tire/wheel tether system or body integrity systems that would keep flopper bodies out of the spectator areas. Biggest safety advance they could make would be to roll back 40 years and institute the Big Daddy rules package (I.e.starts at the end of a run or you are disqualified). They'd get bigger fields in the PRO's and take less time to run, make track prep equal for everyone as well. Instead they enforce non-sensical rules like the belts which chafe at all the sportsmen racers, not all of whom have 500K operations. Wonder how long dragster racers lobbied for a secondary hand brake? Too long....
All that said, it's their rules so if you want to play on their sandlot then it is what it is.
