Respectfully disagree. Your post suggests that motor industry innovation is driven (pardon the pun) by F1. Some of it is, but typically for super cars. Certainly not all of it, or even most of it.
Besides, constraining the car specs in and of itself stifles innovation. How much F1 tech is there in Tesla, for example?
I know very little about Tesla, but quick search tells that its made from carbon fiber, probably has a tyres yes?
Tyres very much evolved because of formula 1. Carbon fiber and a few more. No need to underestimate development in F1, especially when manufacturers itself are involved. Prove of that is that Honda announced coming back to F1 as an engine manufacturer straight after new rules was confirmed.
