As for what would make the most interesting final two races, consider the following scenario:
China Race Results:
- P1 = Kimi
- P6 = Alonso
- P8 = Hamilton
Brazil race Results:
- P1 = Alonso
- P2 = Kimi
- P9 = Hamilton
Unless I'm mistaken, that would result in a three way tie, with each driver having 108 points.
Kimi and Alonso would win the first tie breaker round by having 5 wins each compared to Hamilton with 4.
Kimi and Alonso would continue the tie breaker through round two by having the same amount of second place finishes
(4).
Kimi wins the Championship tie breaker in the third round by having 4 third place finishes compared to only three for Alonso...
Kimi Raikkonen wins the 2007 Championship.
Likelihood? Less than 1% chance, but still, it would make for a wild ending to a wild season in F1.
