As more and more Tesla's become available, thoughts about true availability to the free Supercharging network? Especially in places like CA, I've seen posts about Hawthorne having long wait times, I figure Coalinga and Gilroy to start to become an issue. What do you do if a supercharger is full? Early adopters had free access to them, now that more and more people will use them, will it become like a Costco gas station? I know Tesla is increasing some SC from 4 to 8 or more.... but still hearing about them being full. Are you guys concerned about SC overcrowding?
