I think the problem is the business models. EV manufacturers rely on the gas savings to make their product financially enticing. The battery is the crappiest part of the vehicle. It will be the costliest and fastest major component to wear out. It will be the most toxic for the environment. If it can be recycled at all, it will not be economically effective to do so. If it cannot, safe disposal will be very expensive. Any "swap the batteries" model would expose that EOL cost of EVs because the battery swap company would have to deal with those dead batteries. An EV also becomes a much less appealing financial proposition when the cost is upfront vehicle cost + lifetime monthly cost for battery swap service.
