I'm sure others have considered this as a potential cheap and easy solution to providing the status of supercharger stations, but I've yet to see it discussed. Why not have real-time video streaming of each Tesla supercharger site integrated into the nav system? It would be inexpensive and very easy. It would allow drivers to look and see if the station is fully occupied or not and help decide to use it or carry on to another location. If the station is out of order for some reason, Tesla could easily replace the video feed with that information and ETA for a repair. Personally I would rather see this keep-it-simple solution rather than some complex and glitchy means of routing traffic away from busy stations.
