> Only limited areas of the USA, as evidenced by my recent trip.
For Tesla chargers, that might be the case, but there are a lot more multi-standard chargers supporting CHAdeMO, CCS1 & 2, etc., than Tesla chargers in the USA. Tesla has the biggest single-owner network, but that doesn't actually put them ahead in infrastructure supporting their cars, because they are the only ones relying on single-owner infrastructure.
I did a bit of research along the route I followed, and the worst stretch seemed to be around 120 miles of no charging stations. The rest of the trip typically had them between 15 and 20 minutes away from the freeway.
If I needed to spend an hour (driving off freeway + charging) for every 200 or 250 or even 300 miles, that would have made the drive far less pleasant.
