Direct quote: Light went on to explain designing a perfect run-off and safety net area at NHRA tracks is not easy. “The challenge with our sport, unlike say NASCAR, Formula 1, or IRL is that we have such a diverse group of vehicles,” Light said. “You’re trying to design something to restrain many, many different shapes of vehicles, weights of vehicles, small narrow tires, big wide tires, long skinny cars, motorcycles, it is unlike anything that NASCAR, IRL or any other sanctioning body has to deal with. That has been the challenge for the University of Nebraska to try and come up with something that works effectively for the wide gamut of vehicles we run.” Listening to suggestions and opinions from owners, drivers and competitors is something Light welcomes. Now from what I read he states the challenge is the diverse group of vehicles. See when you look at it like that then yes there is a challenge. The issue is slowing down the energy of the vehicles. Which is definitely where the problem lies. The technology is no doubtfully there. Now how is it going to be fixed?
