The teams are to blame for this too. They're slow to help but quick to criticise. Lotus were the only team to do them a favour by giving them a newer car to test on. Then when the Lotus proved to be light on its feet the other teams kicked off saying it was because Pirelli were using a Lotus to develop the tyres. The logical thing to do in that situation would be to supply Pirelli your own car to test on so they have a broader range of cars to test on to make sure the tyres are suitable for all teams. No. They say Pirelli shouldn't use the Lotus so they now have no test car, presumably they're using and old Toyota or HRT to design next year's. How on Earth is that going to help things?
And Lotus have always been kind on their tyres, so there's no evidence they've benefitted massively from Pirelli using their car anyway, the other teams are just using that as a scapegoat to excuse their own underperformances.
The sensible thing to do would be to bring back a few in season tests to develop next year's tyres. Even if it's just staying on at a track for two days after a grand prix. The teams who take it seriously and try to supply Pirelli with a car which handles and delivers power like next year's car should get tyres they can work with next season. The teams who abuse it and try to use it to develop this year's car, or **** about trying to hide what they've got next season will reap what they sow when the tyres don't work on their car.
