the problem with Motorsport is that the IOC doesn’t really want Machine coming into the equation of driver ability.. (but hey! the have equestrian!)
i had an idea last year about putting Karting on @ the Olympics. Sounds crazy! but it really isn’t.
The Chassis and Engine are provided to competitors on practice day, and there are limited setup adjustments allowed. Every driver is in the same Kart and Engine Package, and the result is down to minute adjustments made my the team (tyre pressures, etc), and driver ability.
Check http://www.maxchallenge-rotax.com/event2011/grand_final.html for an example..
You can have F1 Drivers, Touring car Drivers, Rally Drivers, Karter’s, etc, fighting for a gold medal!
the only downside is that handing out a Chassis and Engine to each competitor costs money.. Normally the Manufacturers provide them free of charge along with advertising, but i’m not sure what the IOC’s stance on Advertising is..
