F1 Driver Rankings

I figure it would make sense to a do an annual F1 driver rankings that my friends can comment on or reply with their own lists. This would also make it possible to have some idea of how drivers are doing from season to season.

2010 rankings (after three races):
1. Sebastien Vettel
2. Lewis Hamilton
3. Fernando Alonso
4. Robert Kubica
5. Felipe Massa
6. Nico Rosberg
7. Jenson Button
8. Adrian Sutil
9. Rubens Barrichello
10. Mark Webber
11. Michael Schumacher
12. Heikki Kovaleinen
13. Nico Hulkenberg
14. Jaime Alguersuari
15. Timo Glock
16. Jarno Trulli
17. Vinatonio Liuzzi
18. Sebastien Buemi
19. Vitaly Petrov
20. Pedro De La Rosa
21. Kamui Kobayashi
22. Bruno Senna
23. Lucas Di Grassi
24. Karun Chandhok

When I revisit this at the end of the season I can see it changing a lot. That said what do you think? Am I wrong about any of the drivers? I think the top 4 are very close in terms of ability and then theres a little gap.
