A lot of households, like my own, have multiple cars. We have a commuter (50 miles round trip) and a family car. We use the commuter for most trips around town (only commutes 2x/week), and the family car for longer road trips.

I don't need a car that can do both, I just need to replace the commuter since that's where the vast majority of our driving is.

Don't try to solve the hard problem of putting charging stations in the middle of nowhere, solve the easy problem of replacing that second car. For that, sodium-ion is more than sufficient. Focus infrastructure improvements on apartment complexes, workplaces, and shopping centers so people who don't have a garage can charge.
