karting is one of the best tools to becoming a better driver. You get instant response from your inputs and there are no computers to dampen anything.
My dad used to race back when he lived in Hawaii, he was two time state champion. We still take out his old kart (Yamaha KT100) every once in a while. It is so much fun. Once I get some money after college I will probably look into a 125cc shifter kart for weekend fun.
