I'm happy about EV adoption but how is the Supercharger network doing in terms of expansion? We recently went to Ann Arbor and basically got the last spot at the Supercharging station there and in Toledo. People who came after had to wait 20+ minutes (before starting to charge). These will take some time to materialize but this can get ugly quickly. Right now it's kind of a first-come first-served honor system, but I can see things escalating quickly into arguments and fights over charging.... Fortunately we have a charger at home so we don't need to use one 95% of the time, but when we do I think Tesla owners have been conditioned to expect to be able to show up and charge conveniently. Wonder if Tesla (or someone else) could create a queuing system at least.
