No true. You obviously missed "Free long distance travel on Tesla's expanding supercharger network" on the order page today. On previous order pages there was text "This allows you to drive for free from coast to coast or anywhere our growing network of Superchargers will take you". Both are a lot more explicit than "Supercharging Enabled".
That said, there such as thing as reasonable expectations. For example, my purchase contract with Tesla say I have to pay some amount of dollars, they don't explicitly say it's US dollars issued by US Federal Reserve, but it's a reasonable expectation and I'm sure an ALJ or a jury would find for Tesla if I tried paying them in Taiwan dollars instead. Heck, the contract doesn't even say it has to be an actual legal currency, so maybe I could find some board game with "dollars" and buy me a few P100D's with that?
What you get in any contract is not like a computer program, 100% unambiguous and written in a programming language. That's why there are legal systems which rely on "reasonable interpretation" concept.
