I think that Hammond was able to drive the F1 car perfectly but he had to
pretend that it is impossible for non race car drivers to drive a real F1 car.
During one to the last F1 races, they showed a, I believe it was an infra red image that showed how hot new tires are when they are put on during a pit stop. These tires were as hot as the worn out tires.
Hammond said that his tires weren't hot enough to have the grip he needed, even tough they used the same
blankets to warm up the tires as during an F1 race.
I know for sure that there are very rich people whom own real F1 cars and drive them around on race tracks, as part of a show. How is it possible for them to drive in Michael Shumacher's and Barichello's F1 car and Hammon, can't?
That blond girl from fifth gear, drove a single seater (can't remember the exact name but it is a single seater used by older retired F1 race car drivers) and she was able to do so without the problems Hammond had.
I know that there are place where you can drive with older real F1 cars, which is very expensive but it is possible.

A few years back, I read an article in an auto magazine that a British car journalist had the opportunity to drive a Toyota F1 car. At the end of the day he was
only a little bit less than 10 seconds slower than the slowest F1 time on that track.
So how is it possible for non race car drivers, to drive an actual F1 car and Hammond wasn't? Because Hammond had to pretend that it is impossible to drive an F1 car.
