Kubica is a driver with clear an obvious championship potential, seemingly team mobile and everyone knows it. One way or another, he’s probably going to be in a championship worthy car at some point.
Still he ain’t mooving out of Renault this year because the markets closed, from Renault Kubica’s only moove could be down. However as an obvious championship contender he does have the right to demand a championship worthy car.
Seems he may well get one at Renault next year (unlikley) or the year after if the teams progress continues. Remember Renault have only prooved they can develop a car, which we already knew, it is quite a different thing to design a car an develop it over the winter.
If Kubica does find himself in a winning car next year, again it depends how winning a car he finds himself in, he will almost certainly stick around with Renault to have a crack at the championships. It depends mostly on the man, Renault will do anything to keep him now, he has a team on the up willing to be built around him. Logically you’d say this is his best choice untill they start to decline. On the other hand, if he finds himself in a championship winning car he will be expected to win it, otherwise the magic may ware thin.
