I've had my Model S 60 since 2014, and did not pay for the unlimited Supercharger access since I don't take enough road trips to justify the $2000 up-front cost. Now that the pay-per-use option has been made available to newer owners, that seems like the ideal solution for me since it costs $0.20/kwh which would cost me about $100/year assuming I used it 10 times using 50kwh each time. Much more cost-effective than paying $2000 (actually 2500 after purchase) for the buffet. However, Tesla keeps telling me that I don't have access to the per-use plan because I'm "grandfathered into" the unlimited plan. IMO this is insulting to my grandfather (rest his soul) who was a nice man and would never have tried to rip me off like that. Is my case so unusual, or are there others like me who would benefit from the use-based payment plan? If anyone from Tesla is reading this, Elon keeps saying you appreciate us early adopters for funding Tesla's initial models and R&D that has let them get to mass market products, but I'm not really feeling that appreciation in a tangible way. How about putting some money where the proverbial mouth is, and letting early owners like me get the same thing that the new kids on the block are getting.
