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.
