Impressive driving, I suppose.
But really, how much do you actually learn by putting a F1 driver in an economy car on a goofy airport racetrack?
It all started with putting celebrities in the car and sending them around the track, then Damon Hill did it.
In that same episode the real learning experience was reserved for Richard Hammond who was put in an F1 car. After some time in formula Renault and briefings he got in the F1 car and initially was driving too slow to not crash because there was not enough heat in the tires or the brakes. He managed two laps, but apparently only used full throttle for 0.2 seconds.
