This might be bullshit but so is the opposite stance you are taking. F1 R&D can contribute, it has done so in the past, it currently does not and will not in the future, as long as the rules continue to DISCOURAGE relevence. A reasonable shift in focus (not unlike what they are doing) to dampen the obsession with aero and increase the emphasis on fuel efficiency is exactly what F1 and the auto industry need.
Not sure that it is actually what F1 needs...
The auto industry is doing that with and without motorsport. F1 won't help much, if at all.
There are many potentially road relevant technologies that have appeared then been supressed - even in recent years, Rotary Valves, AlBe Pistons, Sleeve valves, 2 stroke turbo, CVT etc. Any of these would have seen useful development in F1 if allowed to remain. For the future, F1 can play a useful role in developing DFI, VVT and duration, turbo compouding, KERS etc - if only the regulators, and the the spoilt-brat power-broker teams will allow it.
Many of the technologies that are being put forward for the new F1 were banned to stop a development and cost race by the engine manufacturers. These include DI, VVT, variable length exhaust, variable length intakes, rotary valves, sleeve valves, 2 strokes. AlBe pistons were banned on safty grounds, turbos were banned on cost grounds (that worked

). CVT was banned because it was a detraction to the show - even the V10 engines sound aweful when they drone around at a constant rpm.
Also, other technologies were banned because the perception that they made the driver redundant, or his job too easy - things like ABS, active ride control, traction control, launch control, 4 wheel steering.
Most technologies trailed behind production cars, and I expect they will continue to remain behind.
