"Driving a modern Formula 1 car is very helpful," said the 57-year-old. "And maybe I have another chance to do it with the new engine in the next two months. That would be another good experience.
"I am already thinking about the new technology coming in Formula 1 with the new engines. I am going to work very hard with Renault on that; it is our new target."
Is that even legal? If they can do it then Ferrari should too.
