Actually, the reason I asked, is because I wondered if it was Damon Hill. I saw him on TV several years ago, on some program... where he drove a "normal" car around a track. He was amazing, doing all kinds of stunts with it. He drove it like it was a part of his body, and whoever was sitting with him, was cacking themselves, while Damon was just chuckling and throwing it around.
Not only that, but F1 is such a high standard, I did wonder if it took someone of that standard to get the position of the Stig. And perhaps, it allows them to really test the latest super cars, because they can say, "We have a former F1 champion".
p.s. I don't like really Top Gear either. There is way too much messing about on it. I am not vaguely interested by smashing up caravans or racing across a desert in beat up old cars etc.. I only really want to see fast cars being ragged around and reviewed.
