> There are big sections of the western US (for example) where the existing EV ranges are a dealbreaker

Where? I live in Wyoming. The folks who have EVs around me are doing fine–there aren't many public chargers on a square-mile basis, but there aren't many places the public is randomly going. If you're travelling on a highway, you're passing chargers about half as regularly as you're passing gas stations.

My next vehicle will be an EV. (I'm waiting for non-Tesla self driving to get a bit better.)
