Definately, they could do it ROC style and build a kart track in Wembley Stadium and have past and present F1 drivers. How great would it be to see Martin Brundle VS Schumacher. I think either Alonso, Schumacher or Hamilton would win though, Massa is quite tidy too.
There have been karting events in the recent past that involved a lot of the F1 field (and drivers from other top disciplines too). It's 'organised' by Massa and called International Challenge of the Stars. It would be nice to see a full-field exclusive F1 challenge though.
I nearly posted it yesterday as well, only to notice in last minute that it's just been done.
Other than that I'd like to say that I'm fascinated by that peace of motion picture. I mean on that road car wheel rotation to make such a save it's out of this world! Also it's a must to check co-driver cam, guy didn't make any reaction until Mark asked him a question, fearless mofo really deserved that drive.
