After looking 2 races of Formula 1, in Australia and Malaysia, I think it's not exciting, thre is team using KERS but other no, and the team who doesn't using KERS was win, I think is a bad rule in F1, if the rule is using KERS so all of the team must using KERS, if no, is like this, two big team ( Ferrari and Mclaren )still try to make some change on they car, and I hope they could do the best
