Those choices are a little restrictive and unsurprisingly biased towards American-favoured sports (which is only natural as its Speed).
So I haven't voted on that site, but I'll post my choices here:
Oops moment (not sure if this means human error or random accident):
Human error: Vettel & Kubica tangle Australia 2009
Random accident: Kovalainen flaming Raikkonen
Biggest hit:
Um, Massa's accident.
Best move:
Button's overtake on Buemi Brazil 2009 or Button's overtake on Hamilton Bahrain 2009.
Best finish:
BTCC Round 10 Brands Hatch, race 1
Temper, temper:
Jarno Trulli vs Adrian Sutil
Biggest Upset (assuming this means unexpected result):
Brawn, Toyota and Williams with the double diffusers + failure of KERS. Totally reversed the grid.
Best Rivalry:
Loeb vs. Hirvonen
Audi vs. Peugeot
Best Comeback:
Mark Webber Germany 2009.
Rookie of the year:
Nico Hulkenburg for his GP2 debut season.
