I know a lot of people are riled up about receiving polite letters encouraging charging at home. But lets be real, 1. Superchargers are very expensive to run and setup, but free to use, and as more and more Tesla's are sold, there will be some bad apples who will abuse supercharging. 2. Apartment dwellers NEED supercharging. It's not a nice to have, it's a must have. My suggestion is, allow free supercharging once or twice a month for everyone. Beyond that, I would be totally cool paying a nominal fee covering the cost of electricity, say 10c/kwh. It's five bucks to fill your tank people! You bought a $100K car, surely you can afford $5 to fill it every now and then when you need it. This will, 1. Help Tesla focus their energies on expanding the supercharger network. 2. Prevent supercharger abuse. 3. Stop all this negativity about receiving letters. Add to that, Tesla could have our credit card # on file, you plug in to charge, and it automatically charges your card. What I would NOT be cool with however is, if Tesla starts charging a ridiculous amount to supercharge. They should charge just enough to make charging at home more attractive out of convenience, so people using superchargers, are the ones who actually need superchargers.
