It has some benefits to both consumers and automotive industry.

I live in an apartament block, as do many people. Can’t really charge when parking by the street. If I could go into subscription like service with a charging network where I don’t own the battery outright and just swap it at gas stations that solves a lot of issues. It’s faster than charging and I don’t have to own a battery outright which lowers initial investment. That battery doesn’t even have to have that great of a range either. Car company / charging network or whoever does the battery leasing benefits long term because they can charge more overall.
