I was going to say this is not going to work but thinking about it... it might. Swapping stations will be very hard to build and maintain but it's not exclusive technology, i.e. cars with swappeable batters will still be chargeable. So swapping stations will be like ultra fast chargers. You will have big network or normal chargers, smaller network of fast chargers and tiny network of swapping stations in key locations. If this standard will not make the car more expensive it could be an incentive enough for people to buy them. As more cars can swap batteries they will build more swapping stations. It will not become the main way to of charging any time soon, maybe never, but it could work for longer trips.
