I like Sato... he just shouldn't be an F1 driver.
I think Sato should spearhead the Subaru sports car effort. How about an Impreza STi GTS ALMS program?
As far as "the best driver in F1", I think it's Kimi. He'd be way out in front of the drivers championship if Mclaren didn't have such an issue with reliability. This guy came from dead last on the grid to win! Who else has done that in the modern F1 era?
Now, Alonso's drive at Imola holding of MS was absolutely brilliant, and he backed it up last weekend by passing Michael with the positions reversed, so I will certainly agree that Alonso is better than the outgoing champion, but I think Kimi is the current king of F1, and he'll take the title next season.
I figure, it took a year after Paragon got built for Mclaren to finally get their car to be faster than the Ferraris (the new Michelen tires didn't urt either) and my guess it that by next season they'll have the reliability worked out. All that's left is figuring out a way to let Kimi run right behind another car in the draft w/o losing all his front end grip. Once they get that, Kimi will destroy the field no matter where he starts!
