We also need EV designs where the batteries are modular and easy to swap out. I wouldn't be interested in a deal where I was compensated financially for quickly wearing my non-replaceable car battery out, because the battery wear alters the usability of the car, e.g. I might find I can only take my family on shorter trips than planned, if my battery is now 80% of what it would have been. I also wouldn't want the battery level timed around the grid vs my own transportation needs. What if there is suddenly a heavy demand on the grid, and now I can't take my sick family member to the hospital, because the charge was sold to the grid? |

Battery swapping is already a thing. In China. Nio[1] sells luxury cars and there are lots of more utilitarian vehicles that use battswap, but get no press outside China.
In the west, Ample[2] is working with manufacturers to modularize batteries and make them swappable between vehicle brands, so a "gas station" business/industry model will work.
Edit: I believe that EV manufacturers that don't offer battswap will confine themselves to the luxury niche of the market. The mass market wants low sticker prices on its vehicles.
