It's capital intensive to build the stations, money better used on more super-chargers, development of gen 3, development of better chargers or batteries, marketing, anything! Range is not THAT big of an issue. We already know what we're getting into when we buy an EV. The supercharges already deal with most of these range issues and I have a second car. I can also go rent an ICE for long distance trips if need be. The battery is not a commodity to me. I do not want someone else's batteries if I am taking good care of mine. The whole process of exchanging a third of my car for each 250 mile trip seems backwards, a hassle, unnecessary, and risky. I would really just wait the extra 30 minutes. Seriously, very few people are going to use this and it sounds very expensive to implement. Whats worse is, introducing a better place method of battery swap makes me think Tesla is really out-of-touch with its customers. I was really hoping for a lithium air battery add on pack that can be put into the frunk or trunk, and had a range of 200 to 300 miles. At least, that's workable.
