    Or they could use EVs. Require cars to have V2X (Vehicle to Grid, Vehicle to Load) feature. EV batteries are humongous.

      As a consumer, would you want the extra usage on your battery? Those extra cycles have to cause some additional degradation to the system, but I do not know how much.

        I feel like this is likely going to be a non-issue in practice. Because these batteries are rated to last at least 10 years either way. And by that time, the cost of replacement will be dramatically cheaper.

          They are rated to last at least 10 years (under X usage conditions)

          They won't last nearly that long under Y usage conditions if Y is substantially larger than X

            They're rated to last that long under a full charge-discharge cycle per day. You won't be using them more than that unless you're doing something really crazy.
