Also F1 is supposed to drive teh R&D for regular cars....so going backwards to pure ICE cars is what historical racing series are for.

 

What road car tech was the Lotus 25 or 79 driving? Or the Ferrari 641? This idea that F1 has to be relevant to road cars is the spin the manufacturers put out there so the rules don't have to change. 

F1 is a sport, if it can't provide a decent sporting spectacle because one team has total dominance and the costs are too high for teams to enter or even stay in the sport then all the road relevance in the world won't make it more interesting. And being interesting is what makes it successful.

Arguably the category that has done the most to move forward passenger cars is sportscar racing (ABS, reliability), followed by the WRC (AWD, antilag, etc) of old. Let F1 just be a sport for the spectacle's sake.
