One of the benefits of EVs is we can get rid of a lot of infrastructure. Everywhere already has electrical so home and destination chargers are a minor add on and it’s only superchargers that are new infrastructure. Meanwhile the entire gasoline and oil refining, distribution, and tens of thousands of gas stations can just go away, along with their associated pollution.

Swappable batteries may sound cool but they’re less edficient plus now we have to build up a huge new set of infrastructure agai, we have to standardize batteries, and we can’t build them into structural parts. The only real advantage is speed but that’s not much advantage if you need to drive somewhere. I’ve never had to charge more than 25 minutes at a supercharger, so swapping a battery is only convenient if it’s at most ten minutes more away. Then you’re also assuming there will be more more battery and charger advances, such as those solid state batteries that a couple vendors claim are already in production, such as 800v charging that a few vehicles already can do, such as the latest Superchsrgers that can charge faster than any car can accept so far, or the semi chargers that have a few built out.

Long before you could build out a huge new infrastructure for seappable batteries and standardize cars around it, we’ll already have charging improvements that will make seappables irrelevant. You could argue they already are irrelevant in some areas
