This may have been suggested elsewhere, but thought I would put my 2 cents in. With the congestion I have experienced at Fountain Valley, SJC and San Diego there needs to be a queue system. It would be nice to see the ability as one gets within a certain distance of the SC to have a pop up come up on the screen that allows you to reserve your place in a queue for the next available charger once it becomes available. Maybe a couple 100 ft away. This would let everyone know who is next in line and clear up and potential problems like the verbal altercation recently at San Diego. This could also provide the driver the best stall to back in to at that time to maximize the current pull for everyone charging.
