Just because a particular solution doesn't originate in F1 doesn't mean F1 cannot, or does not, play a role in the development of that solution. With more open regulations or greater scope for innovation, the teams can adopt more true cutting-edge technologies, beat the hell out of them around the racetrack, and eventually those solutions are refined into marketable products because of it. At the very least, F1 lends viability to everything it touches.
This is very difficult to accomplish, however, when everyday, mainstream cars are likely to be more advanced than what we see at grands prix these days. I see cars with direct-injection engines, CVTs, dual-clutch transmissions, magnetorheological suspensions, etc., all the time, just never on an F1 circuit, but it wasn't always like that.
I think it's ridiculous that teams spend millions and millions of dollars to "refine" 20-year-old technology when F1 was built upon an entirely different philosophy.
