This is cool. I hope they make it.

I like camping and hiking 20+ weekends out of the year and end up on some nasty dirt roads, but I also commute to work and deal with city driving a lot. I’ve been thinking about 2 car solutions like a Bolt or R3 small EV plus a beater for the mountains, but if these actually make it to reality then it could do everything I want.

220 miles of range is plenty for a commuter car for a family with a 2nd car with more range. Not everything needs to be a 1 car solution.

The Toyota Compact Cruiser EV concept still lives rent free in my head

Agreed broadly, but I want to nitpick the phone comparison. I had spare batteries for my smartphone for events like all-day conferences/conventions to swap batteries in the afternoon. I could see battery swapping making sense in urban areas for mopeds and ebikes or even delivery vehicles, but there aren’t use cases for personal cars that make sense to me.
