Quick wrap of RKs job today. He said that they were testing things that no one did or normally would with an F1 car to stimulate the car and give some valuable data to all of the departments. He was driving an old PU, as it was not about absolute lap time anyway but doing the stuff to give the engineers some answers. He said why they waited with such move until he got into the car: "of course You don't want to do it with regular drivers, as You don't want to waste time... they need to prepare for the weekend" (I loled at that point) "As I'm not driving, of course I'm the one to try those strange ideas"
Robert said that the car felt pretty good, high speed balance was ok and that it went even better than he hoped, though he added it has more to do with a different track layout than actual car development. He also said that he doesn't know how well the drivers will do, especially given that he has not driven a same car as they will, but a completely different setup than anyone would possibly want to run.
There was also a moment, when Kubica has been asked if there's a cure for a car like FW41: "There is one big cure for an F1 car. It's called the downforce"
Later on he stated that his goal has not changed - he wants a drive next year and it doesn't have to be Williams.
