Heidfeld has been a decent driver all season, able to challenge McLaren and Ferrari on some occasions. Kubica is extremely talented for a rookie, although overshadowed by Lewis... In all, BMW has been great this season, and the main reason for their inability to be on the podium regularly was the lack of really talented and experienced drivers like Alonso, Raikkonen and of course, Schumacher. If McLaren would be banned for the spy scandal, expect BMW to mount a serious title challenge against Ferrari next season.
