If you follow Formula 1, you will know that this years regulations include a fancy new rear-wing option called Drag Reduction System (DRS). DRS is designed to unload the drag from the rear-wing in order to make overtaking easier. Formula 1 has for some time been a bit too “processional”, with very little overtaking occurring in races. DRS and other changes for 2011 have so far, on the face of it, improved the situation considerably. However, I can’t help wondering if DRS may prove to be a bad idea in the long run.  The rule change requires that the chasing car be within1 second of the car to be overtaken just before the start of a designated overtaking zone. If that condition is met the driver of the chasing car can press the DRS button once on the straight; the wing will unload, and his car will have the equivalent of 80bhp extra with which to overtake the guy in front – who cannot invoke his DRS to defend. So far this seems to have made overtaking much easier in the designated overtaking zone, but not much overtaking is going on elsewhere. In the two races so far this season, attempts to overtake elsewhere have often ended in disaster for one of both cars. (Alonso/Hamilton in Malaysia). Surely the team managers are going to instruct their drivers now to wait until they get on the overtaking straight before having a go. This will mean we’ll see overtaking only on one part of the track – which is barely any more entertaining that the overtaking that used to happen in the pitstops. Also, imagine as a driver you are in the penultimate lap, and you are in first place with the chasing driver right behind you. With only one part of the track where you can realistically overtake, you are in the worst track position. You would want to be second on the penultimate lap and DRS virtually guarantees an overtake for the chasing car.
