If you hate sitting in the staging lanes on a 100 degree day, suited up, helmet on, and then have a car oil the track and have to get out and wait 45 minutes for it to be cleaned up, you shouldn't have a bad thing to say about engine diapers or transmission blankets. I wish they had something to cover the rear end too. A lot of tracks have lackluster clean up equipment. You're not at an NHRA national event where any type of oil down is a 10 minute hindrance. You're at some place that just killed nearly an hour of the day and you hope and pray they got all the pieces. Test and tune? No big deal you just lose runs that you paid to do. Eliminations? Your hopes of getting home for dinner just turned into a 9pm or later night with a few of them occurring. As far as the other safety innovations.. get one sideways in grass and watch it dig in and barrel roll and tear the car to shreds. No thanks. None of the stuff required is for when everything goes right. You could drive the thing in the 6's and 200 in a tshirt and shorts with one hand when everything goes right, it's when the unexpected happens that you hope you have everything available to be on your side so you live to see another day.
I'll also be the one to say that I hate it has an ET limit to be enacted because the guy pushing his beefed up but mostly stock engine, trans, rear end is more likely to put a rod thru the side of it or blow the planetaries out of it or shear the pinion off of it than I am and I have already broken plenty of stuff.
