Love this bit from the bbc site....
The new tyres created by Pirelli this year have left all the teams scratching their heads.
One weekend you can be winning, the next you can be nowhere and not know why, as world champions Red Bull found out in Spain, following Sebastian Vettel's victory in Bahrain last time out.
As Alonso put it after the race: "We were 57 seconds behind Vettel in Bahrain, and we were lapping (his team-mate Mark) Webber here. No one understands probably. Not us either."
There is a recognition throughout the sport that this unpredictability is adding to the superficial appeal of F1, especially as the years of Michael Schumacher's domination with Ferrari are not so very long ago.
Nevertheless, there is also a growing sense of unease - largely unspoken publicly until now, apart from Schumacher's comments after Bahrain - that it's somehow not quite real.
The tyres, some feel, are introducing too much of a random element that demeans the sport in some ways. That F1, whisper it, may have gone too far the other way.
Fun, though, isn't it?
