265 miles isn't far enough for you? You also get *free* charging at their stations.
265 miles then recharge at the nearest filling station would be fine. Hell, after 265 miles I'd be ready for an hour's break.
The reality, though, is 265 miles (assuming you're starting fully charged from your mains-equipped garage), minus x miles if you need air con, lights or heating, minus y miles detour to take in the nearest supercharger, minus z miles extra safety margin (because if you run out its a tow to the nearest supercharger) isn't quite there yet. From the map on Tesla's website, there are plenty of US states with no superchargers at all. According to the same map, there are 0 in the UK (which may be out-of-date).
Looking at the UK, there's an OK-looking network of non-super chargers (still nothing like the filling station network), but they're typically 1 regular (13A) bay + one fast charger bay. If you turn up and the fast charger is in use (with the occupants off somewhere having a meal or shopping) then you better have enough charge to get 50 miles to the next station...
Also, since the battery size is determined by the size of the car (unless you fill all the luggage space with battery), having to buy a full-size sedan just to get a > 100 mile range is a problem if you really want a compact. Personally, the Tesla is the sort of car I'd only consider if I was making regular long trips.
There's also a huge scalability problem with charging stations - a regular gas pump can fill one car every few minutes, an EV charging bay can only top-up one car every half hour but by that time the occupants will probably be staring their third Big Mac or in the mall trying on shoes. While EVs are a rarity you can get away with a couple of charging bays every 50 miles, which will probably pay for themselves by attracting wealthy Tesla owners to shops and restaurants. If they take off, you'd be talking about wiring up half the bays in the main parking lot.
I think its great that Tesla are working hard on some of these problems... I wish people wouldn't pretend that they were all solved.
(Actually, I've seen a video of Tesla's robotic quick battery swap procedure, which seems more viable for on-the-go recharges, and would be particularly sensible combined with a battery-leasing scheme).
