Ive always said that DRS should be limited to 20 or 25 pushes per race, drivers should have to use them tactically. And that DRS should be only de-activated on the first lap and the first lap after a SC period.
As for Quali, the drivers then get 3 pushes per Quali session, so if you use it 2 times in Q2 you only have a single push in Q3. This would mean that the top guys would have more of a risk in their strategy.
It should be free of use in all FP sessions, however, the last half hour of FP2 should have no DRS for all cars so drivers can get a handle on the cars without DRS.
DRS should be a tactical thing for drivers to use to attack or defend. However, id make it that the DRS advantage should be not avalable to the leader at all.
Sometimes i think DRS should be banned, sometimes i think it should be used for tactacl reasons. At the moment, i think it should be used for tactacl useage.
DRS is a rule that should be tidied up in the rules. This activation zone/1 second rule thing is a load oo golly twaddle.
If you had a race that in the last 10 laps you had a race where you had say Alonso chasing Vettel, Vettel was doing 1:32s and Alonso 1:31.4s and was only 5 seconds away from a victory. Alonso had 10 DRS activations left, and Vettel only 2. How nailbiting of a finish would that be? Alonso would be on full attack, Vettel having to wait to use the DRS for defence.
Everyone would be talking about the last few laps, and the sport would benifit i feel.
However i also think that the DRS flap and mechinism should be standardised to a point. Say every team had the same 5 flaps for a race season to choose from and the mechinism was standard, theams would then be looking to make their cars as drag free as posible. For this to happen, id allow a slight change in the rules to the diffuser, id probably raise it from the current 120mm (Am i right?) to 125mm whitch would give a slight recoup in downforce, but not much.
