Is Schumacher Really The Stig?

A lot of speculation to be honest... Many people think that Schumacher is not the Stig and that he was in fact set up as a joke. It seems possible really, especially seeing as right at the end of the episode Jeremy Clarkson said "I don't think that Michael Schumacher is the real Stig."

Also, this has been a theory for a while now, but many people think that the Stig is in fact several people and not just one. To be honest, I don't see how this would be any good to the show. The idea of the Power Laps, Stig's time to shine, are to get a fair and accurate time out of a car on the Top Gear Test Track but it wouldn't be very fair at all if it were several different people, all of whom presumably have different driving styles. The Stig manages to keep a very consistent style while driving cars around the Top Gear Test Track, so personally I throw that theory out of the window and continue to believe that the Stig is just one man, whether he is Michael Schumacher or not.
