To provide a 300 mile range with today's battery technology means carrying around a lot of weight. Why does Model S need a 300 mile range? Based on all available data a daily range of 100 miles would be more than adequate for 99% of the population's needs. Providing for 300 miles requires using power to move the extra weight of batteries. This is clearly not an efficient use of electricity and coal. A Model S owner needing to go across country could (most likely would) rent a vehicle. Secondly, the luxury fitments of Model S (and Model X) also add what I believe to be unnecessary weight. An example is the complex motorized door handle which is nothing more than a designer's whim. Model X is a behemoth waiting in the wings. Heavier still than Model S and burning even more electricity and coal to move tons of car and usually only one occupant. Step back for a moment. Sure Model s is a beautiful looking car and will have great performance BUT... Is this really the best way to spend 500 million of taxpayer loans. I for one would have been much happier to see a small commuter vehicle that truly could help to save the planet and the pockets of the middle class. The annoying thing is that Elon Musk and the engineering team could have pulled it off. Instead they chose ego over eco and built a luxury saloon for the wealthy.
