The worst part is they’re nowhere near: the effective strength of Tesla is that they built a large and reliable network of fast chargers. I don’t know how non-Tesla charging is in the US, but in Europe it’s still a complete mess of half-assed crap, meaning if you don’t have a Tesla you either simply can’t make trips beyond a single-charge round-trips, or you have to plan the trip for days in advance poring over maps and fallback chargers like it’s the 60s and you have to account for 50% odds of needing to rebuild the engine on the roadside.
Not “green book” bad, but absolutely “get close to hurling from the stress and triple travel time because you had to hypermile to reach the charger then it was worse than a home socket”.
