Japanese daily commute is like 10km for a roundtrip, even for rural areas. A 10kWh battery will last days in such usage regimen.
It’s not that all car sales happen in Tokyo (far from it) and there’s a lot of Tesla’s etc, but why buy a car that you would only be able to use for a daily commute and not for trips that go much further than that?
10kwh according to Google gets you like 80km. That’s pretty minuscule and would preclude even short weekend trips.
The fancier is the car, the less people drive it so they can sell it at higher value.
