I believe that battery swap was effectively a scam. There was some arbitrary full recharge time that had to be met to access some rebate program, and Tesla did exactly as much as they needed to do to meet the terms and then stopped.

Electric cars are the future, and Tesla's are cool, so don't take this as a negative. The complexity of battery swapping was in ownership of the batteries, not in the physical swapping. It maybe makes sense for big taxi firms, but not for standard consumers.
