In a recent interview, Scott denied any interest in returning to F1. I still maintain that he is worth USF1 going after (and they did say they were looking at him) and that he could be persuaded to change his mind. As the only active Stateside driver with recent F1 experience, he has to be on USF1's list.
As for the tyre-warming comment, I suggest that those with a low opinion of Scott's abilities take another look at his record in F1. He was comfortably quicker and more reliable than his team mate, Liuzzi, in his second year and was showing enormous potential thanks to his ability to learn. It is not his fault that he was employed by a team that regularly rubbished its drivers and proved completely unable to understand American. USF1 will not suffer from such deficiencies.
