Tesla did that for a while. They abandoned the plan. Batteries are big and heavy. It turns out to be far more important that engineers have the ability to fit them around the other parts (suspension...) than the ability to swap a standard battery.

Yep, the batteries are ridiculously heavy and they’re used as structural elements in the car.

So swapping batteries is hard to do, and unnecessary for most drives. Sure, you’d want to be able to swap batteries in five minutes like pumping gas. But who’s going to ship batteries out to the middle of Kansas, build infrastructure, and pay technicians just for people on a road trip who want to swap batteries?
