They should add a feature where users can virtually “get in line” for the next available charger. In some places, it’s not practical or safe to physically line up a bunch (or even a few) cars waiting for the next available charger. It’d be nice if the app would just let you virtually queue for a charge, so you can go park somewhere close by. Maybe have it set so once a charger is available, you have a few minutes to start charging, or you lose your place in line. If somebody else physically pulls into the charging spot, it wouldn’t let them charge, and would ideally show a notification on their app that X number of people are in line in front of them.
IMO, the simplest solution is to just build the stations, and re-work existing stations, so that they provide a place to physically queue up. This would be easier of the charging stations were built with a pull-through design. If there are multiple groups of chargers, there could be multiple queues.
