Dario Franchitti or Gil de Ferran would be great for F1, maybe even Tony Kanaan.
Personally, I'd like to see more Brazilians/South Americans in F1 racing, 'cos they're always so competitive and entertaining. (Thats why millions of ppl love Barrichello, da Matta and Montoya.)
Funny thing about Cristiano da Matta....in 2002, he absolutely dominated CART racing, the same way Schumacher did last year. OK, granted he's only been in a few races, and he's in a different Toyota car, but I just expected more out of him..I didn't expect him to be a lap down in pretty much every race he's finished.
It's like, he was the best out of 2nd rate drivers last year (CART), but when it comes to F1 racing, they're in a complete league of their own.
The only thing that helps me maintain my slender grip on reality is the friendship I share with my collection of singing potatoes.
