Kubica would appear to be jealous?
Definitely.
I think in 2008, Hamilton is a rare breed of old-skool drivers who wants to be fastest, at all times, in all sessions, simply because he can (and also because he has a massive ego). The drivers of late have become too "smooth", in that they dont want to partake in the rough stuff and they tend to shy away from wheel to wheel racing.
Imagine if Mansell (at his peak), raced against these guys. They would be asking for him to be banned!!!
Soon, drivers will be asking for overtaking to be banned.
I think its refreshing to see such an aggressively fast driver using race craft to put the manners on his peers, on the track. This is the way it should be done. I'd like to see Alonso in a fast car though, as I think now he will be prepared to play rough and in 2008 we have been robbed of potentially the most spectacular racing that F1 would've provided in the past decade or so.
MS's racing style was very clinical and (most of the time), lacked the excitement of a Mansell, Hamilton or Senna and I think a lot of the drivers who are in F1 right now, believed that that was the way F1 was heading. Hamilton has come in and has returned F1 to what it was before MS. Hopefully, the rest of the field will follow.
