So we need a modular DRS?
I'm not trying to be ignorant here, it's just that every time F1 has a big rule change one team gets it right the first time and dominates for 4 or 5 years. Only when the rules generally stay the same for a long period is when teams get really competitive, like we saw last Sunday (Red Bull fighting a Merc, Ferrari, Mclaren, Toro Rosso and Racing point!).
F1 is finally getting exciting again, don't have big rule changes, just do small "artificial" stuff, please?
