I could see it being more useful in an area with a large metropolitan area or many closely spaced towns. In a more sparse state like NM, that extra 90 miles round trip isn't big enough to make much of a difference, unless charging stations expand significantly in the future. We bought it knowing full well that we would take our other vehicle out of town most of the time.

There are some attempts to make normal cars electric. The current one is VW Golf, it's small but it's a regular-looking car that also has a fully electric version.
