Email release today indicated ALL vehicles purchased after 12/31/2016, will only be given 400 kw of supercharge credits (roughly 1,000 miles) per year) at no charge. Any amount over that will be at a cost.
If you read the entire blog, it goes on to say "These changes will not impact current owners or any new Teslas ordered before January 1, 2017, as long as delivery is taken before April 1, 2017.: in other words, since no Model 3's will be available at that time, ALL MODEL 3 Tesla's will have to pay for the vast majority of supercharge use.
I do not think that is fair. We bought these cars before this charge was announced. In my opinion, I do not believe this is acting in good faith on the part of TESLA, a company which I believe has the utmost of good faith and intentions to help the world.
Yet, as a consumer, I feel this is screwing us.
