None, i would like to see NHRA tighten the rules on what drivers should wear at NHRA sanctioned tracks, these small tire and big tire races with power additives like nitrous and blowers/turbos. These cars are getting super fast w/stock wheel base, have control issues basically dangerous but fun to drive and entertaining to the fans. I also would like to see emphasis put on fire walls, this particular car had a lot of carbon fiber and it just melted and let fire come into drivers area, i believe he touch on some of that in interview.
