I think this year is very demanding in terms of "cockpit load". Besides the ARW, you have:
► the Pirellis that have to be "caressed" or you lose them quite fast (they'll give you 100 km, perhaps 150 tops)
► you'll have more talk with the team (because of team orders allowed)
► you have new full set of strategies in terms of fuel saving: now, fuel saving could be detrimental in the end
, unless you gamble you will be able to effectively save it (by using the ARW more than the rest of the field as I argued before by being "towed" by your partner or somebody else) an you place your bet on starting your race with less fuel.
► you have half the down force compared with three or four years ago, so you have to "tip-toe" a lot (besides the considerations of taking care of the new tyres, as Valencia proved)
► the car has a bit more of top speed because it has less drag, because you have less down force, so the car accelerates faster
► most cars have KERS (the "push to not
be passed" button, as my friends call it in Indy Cars) so you have to be thinking about the amount of charge the thing has and when to use it
► you have a car that weighs more (20 kilos) and, on top of all that,
► you start your race with a truckload of fuel!
What do you suggest, X? Perhaps if they have to juggle while they drive...
I think, segedunum, that activation zones are there because of safety. Would you want to have Pérez one tenth behind you in the braking zone without down force?
