> The cumulative storage available from the EV fleet is so large that if it were all available, it would saturate revenues in the power system. This means there is likely a limit to the share of vehicles that charge bi-directionally.

Having too much EV battery capacity available to support grid energy storage seems like a very nice problem to have and should further boost investments in wind and solar. I hope that bidirectional charging ports become a requirement on all high-priced future housing.
