It's all part of the problem, some of them weren't good enough, the car and tires were quite complicated, but I'm sure many ppl inside the teams will acknowledge the fact that it's still quite a big step to go from 220 or 280bhp to 600bhp w/o powersteering! If F3 and GP3 are 400bhp, it will be a much smaller step to go to GP2 and yeah, it'll again save on damage bills. Bianchi is really a good example, he had quite a few big unnecessary crashes in GP2, while in F3 I don't remember any such notable crashes and I'm sure Van der Garde doesn't
