I have often said that the key to better racing is change the emphasis of aero from the upper body work, that results in the myriad of flaps and horns and stuff, and use the floor of the car to produce as much as 75% of the total downforce. Downforce produced this way creates less rportianolly less drag and therfore less turbulance to foul up the front wing and aero of a following car, which wouldnt be to heavely relying on the wings anyway. It wont make overtacking easy, but it will make more of a chance for passing. Just my 2 cence.

Some simplistic ideas:

Limited venturi tunnels under the car - they worked well in CART when tightly regulated so should be fine in F1. It's not really a case of porducing less turbulence, the venturis tend to re-laminarise the flow and thus are more efficient at producing downforce when closely following a car.

Banning of any aerodynamic devices on the upper body of the car above the horizontal plane of the wheelnuts between the vertical planes of the rear of the front wheel and the front of the rear wheel, including aerodynamic suspension parts. Cooling chimneys also banned, as this would force bigger radiators to be used, hence more drag and a larger tow for following cars.

Slick tyres - no brainer really.

A lot of people here seem to be suggesting F1 go backwards. Steele discs, flats, wider cars, manual gearboxes......Why not just bring old 70s cars, might as well, because that is what some here are describing.
I always though that F1 was about being innovative and pushing the envelope. I would love to see more passing, but not at the expense of innovation and development.

Yeah, will that mechanical force of steel brake system would be able to work effectively for the speed of F1 car.

Then you'd have to bring back old circuits, and some mightn't like that


Most of the regulations don't allow innovation anyway - any improvements that are made are generally as a result of hours in the windtunnel and not by some bold, Chapmanesque design ideas.
I don't think replacing the aero with flat wings (or no wings) and making the engine rules less restrictive wouldn't hinder innovation any more than now. Should improve passing as well.

Another thing that hinders overtaking is drivers who block other drivers, but that's another issue.

What I was getting at seems to be the asame as you, the shift of emphasis on downforce production from the upper bodywork, which seems to be far more sensative to changes in the air stream (like turbulance from the car infront) to the floor which seems to be less sensitive.
