So we all watch the races and form our opinions. This car is good, that car is bad, this driver is dragging a bad car to the front etc etc. I would love to see something like an F1 track day, where all the drivers and teams show up and like, pick their car out of a hat or something. Get Alonso in a Caterham, Perez in a Mclaren, Glock in a Red Bull, or whatever combination. It would be a great way to see how the back field drivers handle a race winning car, and how fast the best drivers could really make the back markers/midfield go.
I know this will never happen because of the money involved, and secrets you might learn from driving someone else's car. But it would be amaaaaaaaazomg to see I think. Also, it would give the back teams a sense of where there COULD be if they could afford a top line driver/didn't have to take a pay driver.
