It sounds as though the problem is simply that the car loses range unexpectedly depending on the weather, so you can't necessarily count on the range you thought you had the next morning, and the degree of mile loss can be extreme. I imagine this is a problem for road trips, the occasional camping trip or overnight at a friend's house, or even when using an outdoor parking lot for eight hours (e.g. when at work or at an offsite). However, for daily commuting, it's not an issue, because presumably there is sufficient buffer if you charge every night. What's a bit disturbing about this article isn't the laws of physics, but that he was being coached directly from Tesla. If Tesla HQ can't coach a reporter 1:1 out of a devastating result, what hope does the average early adopter have? Either the reporter twisted the facts, or the car has horrible temperature problems, or the Tesla coaches seriously screwed up. I hope it's not a real issue. A hotel manager might be able to let one Tesla plug in overnight, but there isn't infrastructure to let ten or twenty Tesla owners do the same--yet. However, just as wifi became a competitive advantage to offer at hotels, so will EV charging stations. Perhaps even pay parking lots will begin to offer them.
