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.
Mercedes is doing this for their new stations, with lights that tell people that the port is reserved. The chargers can be used by anybody, but the reservation system is only for MB cars.
