Interesting comment from Franz Tost, saying that reducing F1 downforce levels would make it easier for cars to follow, harder to drive through the corners and increase braking distances to promote overtaking.
For me, this would make watching F1 much more fun, and I suspect it would take more driver skill to control the car when it is more likely to slide/drift. Plus, the significantly reduced wake would also make it easier for cars to pass.
Increasing aero downforce is a dead end practice. F1 is slowly beginning to realize that. Far too many aero devices hung on the cars now, including worrying about ground clearance height, etc. The cars have become pretty weird, with wings, fins, boards underneath, what the hell. I say strip all that cr*p off but keep the very safe body.
