Gordon Murray is on the right track with his simplified Formula 1 ideas. Make the wings effectively neutral (for appearances’ sake for the crowds). Allow underbody aero — but require a minimum compressed ride height so that road undulations can be handled; get rid of carbon-fibre brake discs; move to the larger wheels and narrower tyres and then let the manufacturers go for it.
Set a generous displacement limit, but free form as to engine configuration. No DRS, no hybrids. This will emphasise the differences in drivers, and the manufacturers of engines and cars. All of these changes have far more relevance to what is driven on the street now and in the future.
