There have been more torn up karts since the plastic bumpers were implemented than before. Why? The stewards cant see everything, its easy just to punt and run, drivers dont have to learn how to pass anymore, and a complete lack of respect especially from those racing on Daddys money. It doesnt help that two of the greatest drivers of our time, Senna and MS, had a crash to win mentality that has become the norm. The tag sr. Class at any big race has become a joke. When indoor karting is cleaner than a national kart race there is a problem. My solution. Ditch the plastic rear bumpers. Let drivers learn how to pass and learn consequences. Land on your head once and you will think twice. For those that dont learn that is just Darwinism. You cant fix stupid.
