The idea that there is any significant relationship between what makes a good production car, even a sports car, and a racing car was always dubious and today is frankly nonsensical.
The way to make a car fast round a race track basically comes down to the amount of downforce it can produce, and the power of the engine. Downforce is almost completely irrelevant to road driving, as taking corners fast enough to generate cornering forces of over 1G is frankly suicidal on the road.
As for engines, aside from the fact that the internal combustion engine is doomed in road transport (despite what the current administration thinks), producing an engine with performance that exceeds what even good drivers are capable of handling without electronics doing the job for them was solved at least 20 years ago, and continues to be a solved problem despite tightening of emissions standards.
In any case, while lighter, smaller, lower cars remain the preferred option for motorsport applications, all anyhbody wants to actually buy, particularly in the United States, is gargantuan SUVs and pickup trucks, which makes any application of motorsport technology for the road moot.
There is no power-network in existence, not in the medium-to-long term, that would allow tens of millions of cars (mauve hundreds of millions if we talk at the continent-wide level) to get all electric, the physics isn’t there and it won’t be. You’re correct though, it could be that the next US administration will try to copy the bureaucrats here in Europe and try to go the let’s-ban-the-petrol-engine route, which would, in practice, mean that only the well-to-do consumers (like most of the users on this forum) will be able to still have personal cars.
