My vote goes to Killer Kobayashi. He always seems to be there in the
main pack (or second pack) of leading cars while his team-mate, and
other cars that qualified close to him are always way behind. Hes
given Schumacher fits and even roughed up a Reb-Bull a few times.
If Kobayashi keeps this up? He will be driving for a top team next
year. Rosberg/Schumacher, Massa/Alonso, Heidfield/Petrov, Webber,
and Button will all get beat if Kobayashi were their teammates imo.
And given equal equipment Im not 100% sure that Vettel or LH would be
faster than Kobayashi.
