Jarno Trulli is on his warm up lap, putting heat in the tires. I was struck by the relative violence of it all, no pussyfooting about there from the Toyota driver.
One could use this video to illustrate friction circle theory quite graphically to performance driving students: There are times when Trulli, in a corner, whips in more steering and you can see this has almost zero effect on his trajectory.
It is also an illustration of how stiff and under steering Formula 1 cars are set up to be. At low speeds, with low aerodynamic loads, a gentle touch is needed to maintain adhesion.
