From Tesla's letter to "frequent user of local Superchargers" :
SC network's intent remains to expand and enhance your long distance travel while providing the flexibility for occasional needed use during local trips.
Standard Feature for Model S and X as listed on Teslamotors.com:
Free long distance travel on the Supercharger network
It took Tesla over 3 years to get to 60K in the USA, Tesla will most likely sell close to 40K in the US in 2016 alone. The numbers of Tesla's sold is increasing rapidly, especially with the Model 3 coming and greater manufacturing capacity.
Extension of the SC network continues to happen, but Tesla is building very few SC's that are in close proximity to existing SC's.
Look at the comments on
plugshare.com, those indicating that all stalls are filled are becoming more and more common.
Bottomline: if free charging continues as is, the amount of SC congestion will increase
It would be interesting to see how Tesla and Tesla owners react as waits at SC's become more common. Think about how much it costs Tesla each time someone fills up too.
I want Tesla to succeed wildly. It made sense to charge $2,000.00 for lifetime access and to offer it included in the price for early adopters, but the sooner it stops the better. (Thank you all you early adopters for keeping Tesla afloat) Giving out free electricity to the hopefully millions of Tesla drivers in the future is not good business sense.
SparkEv's blog about free charging sums it up pretty well:

I happen to have a Spark EV myself, and anticipate getting a Model 3. There is an SC in the city I live in, right next to some restaurants and shops I like to eat and shop at, I even pass right by it every time I drive to work. I am more than willing to skip free charging close to home, and am willing to pay actual electric rates or even more at a SC, especially if it will cut down the chances of having to wait for a SC when I really need to use one and allows to Tesla to build even more SC's everywhere.
