Unfortunately, more and more charging stations are switching from "free-to-use" to "on-condition-of-patronage".
But us Tesla owners don't have to worry right?
We can use the SC's and not pay a cent. No need to use public charging for the most part.
I think we'll begin to see "pay for use" stations become more popular as well. <snip> Many of the "patrons only" sites will let you charge, sometimes for free or sometimes for a small fee.
I use my purchasing power to provide incentive for businesses to provide charging. Whenever I visit a mall / hotel or other destination with charging, I plug in to ensure the # of uses of the charger is incremented by one, and I tell someone in the establishment I am visiting and using the charge station.
Restaurants and hotels provide free wifi, free big screen TV and other bonus features to compete. Charging is like any other bonus.
Wifi as for these it doesn't cost anything more if 1, 10 or 50 patrons use the service.
