Fighter style cockpit canopies would be worse in the rain or bad light conditions (no flying by wire in F1), not to mention sun glare in good conditions. Plus if you are locking a driver in an F1 car, you're going to need fire suppression systems and likely ventilation systems would be required. They have to be able to get out on their own within something like 3 seconds (not sure what current requirements are, but something like that). Bend the car and the canopy jams - then what?
Fighter cockpits enclosing the driver makes F1 cars into sports cars.
The day they enclose the cockpit or the wheels is the day I kiss F1 goodbye.
I just hope someone from FOM or FIA does monitor sites like GPWiz they might get the message about messing with open wheels and cockpits.
Rant over, I feel so much better.
Still doesn't mean I like these stupid forward cage hoop things, might be fine for Top fuel dragsters
but there's no similarity really between the Drag cars and F1 machines.
