The dangers of an in-season testing ban.
Ferrari have an empty seat after Felipe's accident, but their test drivers (Mike and Luca) have never tested the actual F60. I just think that it is an unfair expectation for a driver to come to grips with a new car in 3 practice sessions and qualifying before getting into an actual race.
I think it should be stipulated in the rules that the reserve drivers can at least have a test session during the season to better develop the cars, obviously, but more importantly have a seasoned driver waiting in the wings.
