US has ~250 million cars. If they are all EVs (100KWh), it is 25TWh capacity.

Reserving 20% of that capacity to supply power back to the grid is 5TWh.

EVs can be charged for free during the day, ~20% of solar is lost due to curtailment. Even if a significant percentage (10 - 20%) of the people decide they are going on long drives from Florida to Vancouver and turn off supply-power-to-grid-for-money in the app, its fine, there are plenty of cars. It is the cheapest, most resilient, distributed and self-healing energy ecosystem. Only one problem, it won't make the super billionaires money. Unless it can be packaged in a way to make the super billionaires money, its a no go in US.

This infrastructure buildout costs nothing, people buy new cars all the time (~20M/year), just buy EVs instead. Because people are providing the capital and the storage infrastructure, they should be paid for it.
