Lewis doesnt bitch about tyres and the Fduct. he's not so stupid as to waste his time on that in a race. He's questioning and giving back information. I think the true feedback will come at a debrief not when you're driving by the seat of your pants, at that point you need to give and receive vital information. Who sets the car up best? I think that varies with the track. Leiws tends to drive round problems. Jens tends to try to preguess them.
Lewis Hamilton complained about having no grip on a few occasions; and that's what we heard on the TV coverage, how many other times did he radio back to say the same? I respectfully disagree; Lewis was moaning for moaning's sake; the team can't do much while he is out on the track; say it once and get on with what he is paid millions to do; drive a F1 car to it's limits! What good is feedback in the after race debrief? that feedback is needed during FP1 and FP2 to set up the car for Q and race sessions. Discussing setup after the fact is useless as it'll be another year before racing on that track again and more than likely the conditions will be different; also different regs and tyres.
sorry if this a biased view, but i dont belive he was bitching over the radio about his tyres and the asking whether the f duct was working, he was just letting them know, i know that the pit wall cant really do too much apart from putting fresh rubber on and hes actually given them things to think about
why are the tyres giving no grip etc and according to bridgestone on formula1.com the track temperature rose significantly which didnt help the tyres condition either and then as soon as the SC came out the tyres returned to normal temperature
