Not quite, he only did 4 races I believe. Canada and then the final 3 races.
Personally Glock has impressed me the most. He's easily been the most consistent of the rookie drivers and he hasn't been too far off Trulli (who is one of the quickest drivers over one lap) in qualifying.
Next is Nakajima, generally gets the car home and has been steadily improving with each race. Fairing pretty well against his highly rated team-mate.
Bourdais has been solid so far. He only managed to get upto 4th in Australia because the FIA opened the pitlane under the Safety Car earlier than the rules actually stipulate. The impressive part of the performance was staying there infront of Alonso and Kovalainen.
Piquet has been by far the worst of any driver on the grid. His qualifying has improved a lot since Melbourne but this guy is so at sea in the races it's unbelievable!
I see a fairly decent future for the first 3; Piquet needs to improve a lot if he has any long term F1 ambitions.
