You're absolutely right here - DRS is just a little too short to be useful without a massive pace disparity between the two cars (attacking car is on far better tyres, for example). Hamilton has said that the point where turbulence kicks in is about 1.1 - 1.2 seconds and I have reached the same conclusion this year. Formula 1 should seriously consider mandating reduced aerodynamic complexity. It might not be a great solution, but it's a better alternative to artificial DRS and snooze-fest races. For what it's worth, the Sauber, Toro Rosso and Haas cars had a great battle last race. That said, turbulence affected them too, almost as badly as it did the front-runners.
