An American driver in F1 is a distant dream. There are 0 drivers in F3000 the primary feeder series into F1 from the 3 last year who did horribly. The Red Bull search IMHO is crap because you need the drivers to go through the ranks. The US has Cart which is the only major open wheel road racing series whereas Europe has tons and tons of open wheel events. Europe has scouts that walk the go kart tracks looking for talent, in the US its all about Nascar.
