Thinking about how lines typically form at gas stations, it is clear that that model doesn't, and shouldn't, apply to EV charging (as long as charge times are >5 minutes). Indeed it should be first come, first serve (to the location). I'm not saying it has happened, or will happen, but it wouldn't surprise me to hear of cases where second to arrive says "You wait for the next one to open up over there, and I'll wait for the next one over here" (effectively splitting the line). The problem is that many charging stations don't have much free space for a single file line of cars to accumulate. Thus, the idea of assigning positioning in line, and thereby allowing cars to park out of the way until their turn comes up, may be necessary to keep the peace, especially once the Model 3 is out. Line position displayed on the main screen would be great. In the meantime, we should all just agree to exercise our most polite selves when approaching a supercharger.
