aptera could eventually offer a "muscle car" that can carry smaller such trailers, which doubles as a sports car.
https://www.quora.com/Is-it-legal-to-not-have-a-permanent-address-in-the-United-States for now RV living isnt common even though it could save a lot of money vs permanent homes, probably b/c RV people have to be allowed to dump their sewer stuff somewhere.
but i imagine this may become a new way of living as cost of living increases, although compact dense apartments would probably beat this from becoming more common for the same reason centralizing factories is more efficient than separate factories ex. thermal insulation.
at the same time, cost of taxes may outdo cost of traveling to another place for cheaper taxes, and government papers could one day be simplified as a service if enough people, such would incentivize government to have minimal taxes when competing for taxpayers. cost of travel could become much less enough with more efficient reliable vehecials.
smaller home also means less energy used for heating lighting etc, thats good for enviromental issues which is sort of the point of electric cars
