F1 has never been about making just the stupidest fastest cars possible. It's always been about doing that WITHIN the regulations. In the past there were fewer regulations because there were simply fewer things that were possible.
First and foremost, it's motor RACING. You might have forgotten that, seeing as we've had so little for the past few years. The regulations mean the cars are designed just to be able to go quickly, with pretty much the only passing happening in the pits. There's far too much dependency on aerodynamic grip.
Ditch the aids, ditch the grooves, widen the cars and drop some aero. Not because it "takes skill away", but because it's what the racing needs. Everyone saying technology has ruined he sport, do you want to go back to synchro-less gearboxes, cross-ply tyres and drum brakes?
