Testing supremo and new Super Aguri signing Anthony Davidson has been talking about his new experiences on the Bridgestone tyres.

"On my last run from the first day I got caught in traffic, so I had to back off. Then I had to attack again, but I had lost all the heat in the tyres and all the grip had gone."

"They slide a lot more. It tests the driver more actually, it really does. It's not more physical, in fact I would say it's less physical because we're going slower. But it's difficult to make them work, on the first lap, especially in cold conditions."

"It's not dangerous. In some respects it's quite fun, but it's just difficult to try to get the car to work and to work the tyre."
