I agree with the need for some certainty here.
Assuming we indeed buy a Model S or X as hoped for, I anticipate we'll regularly use a Supercharger that's about 40 miles away. Particularly as we live on a high mountain, we'll often need the extra charge when returning from various destinations. I'd have no problem paying to Supercharge, but whatever the rate is, it should be no more expensive than gasoline for, say, a 25 mpg car. Better would be if it's on par with gasoline for a 50 mpg Prius. Collecting more money for charging than for gasoline seems likely to dissuade many from considering EVs, especially since Supercharging is still not nearly as fast as pumping gas. Considering the true, high cost to Tesla of installing and maintaining Superchargers, though, I suspect that even with a reasonable fee schedule in place, Tesla will still have to subsidize the SC network.
