I'd like to reinvent cup cars.
Take the trucks, flip the front of the glasshouse from A-pillar to B. Then add a 1970s aero-warrior wing.
I'd also narrow cars to 72 inches, remove rear diffusers, reduce the width of the tyres, and raise the ride height to 4 inches.
Then:
Can we have station wagons back on the roads and kill all fake SUVs?
