I think most agree that he is a quick driver, but as we know, it's not all about raw speed . He has made horrible mistakes this season, but IMO he was arguably worse in his debut season. His debut season was not even a full one so not sure if that counts as a debut proper. I think he will grow out of this phase of unsophisticated driving and become one of the best drivers in F1. I think it might even show as soon as 2013 if he retains his seat. (That was a bold statement). Other drivers are quick like Maldonado, dependable like Kovalainen, basic like Rosberg, but Grosjean has that thing somewhere inside him. He needs coaching and he will be! He will be!
