I find this kind of comments so stupid. The technology is well beyond proven. Logistics have had swappable batteries for over 15 years since the time of acid batteries. Nio is a rental company first and for them the model seems to be working. It's compelling for road trips specially since most of the charging stations are broken most of the time and for extremely dense cities where people aren't allowed to access power plugs at parking spaces. I mean, on the suburbanite hellscape, charging at home will always make more sense, but the US is not the entirety of the world. This things seem to be ripe for success in Asia and Europe.
