This is like saying that Sony can make an mp3 player, so the iPod isn't competitive in that market. Or that a 5GB iPod won't hold enough music, so it's just an expensive toy. Within 5-10 years the battery problem will improve, especially if there is demand. This is technology, not automotive development. We're not in Detroit anymore. They're in a different class. Tesla is set up to do it right from the start at a muc…
Its a bit presumptuous to say that Tesla is so different. Sure, they are attractive at the moment because of unique niche they are filling. If BMW, Mercedes, Audi, Lexus, Acura, etc all sold an all-electric vehicle with similar range, Tesla's differentiation becomes much less unique, and normal competitive factors come into play (scale, marketing, etc).
Standing still while "the powers that be" catch up seems oddly unlike a company with such an obvious culture of pushing the envelope.
