The flip side of this coin is how annoyed some Volt, Leaf, Plug-in Prius, etc. owners get when a Tesla is plugged into a L2 spot because they know we are doing so, more often than not, because we can charge there, not because we NEED to charge. This is a brave new world that, as mentioned above, would be much easier to navigate if the infrastructure was better. I think, honestly, the long term solution will be to eliminate free charging completely. You get charged for the energy you use and additional hourly charges while connected. Suddently Tesla owners would think twice about "just topping up", Volt owners would move their cars as soon as they were topped up, and Leaf drivers would probably just charge at home.
