One thing that has me scratching my head about charging is this: If the supercharger option costs $2000 on the 60kWh and is included on all 85 kWh batteries-- what's the point of spending another $2700 on the HPWC and twin chargers, which essentially amount to an inferior charging option compared to the onboard supercharger?? The answer is of course is that you can't install a supercharger in your own home, and the technology will likely be extremely tightly controlled by Tesla. That seems like a bit of a waste and a shame to me. I'd like to be able to use the supercharger technology on my own-- and why not open up the technology to 3rd parties too? Seems like it would only increase the value of the car by opening up more and faster charging opportunities everywhere...
