Good point, I didn’t rate Kubica’s Spa driver that highly, he lucked out an had the oppourtunity to do better, however he was sensational in qualifying.
Point remains though, Kubica lucked into 1 podium, Rosberg lucked into all of them. An Australia and Monaco where far more impressive from Kubica then say, Sliverstone and Malaysia. Kubica has also done better when things haven’t worked out, Singapore being quite sensational, do you think Rosberg might have pulled of those passes?
As had been said above though, Driver X compared to Driver Y threads must be subjective if they are in different machinery. My opinion is that Rosberg has done a solid job and moved up the ranks when others have retired, while Kubica has forced himself into contention and made his own luck.
