Been seeing a lot of discussion in threads about etiquette around charge stations and superchargers. Is anyone aware of an app that allows you to find out how busy a charge station is, and if it's full a way to wait list yourself or post how long you'll be? Ideally, before I pull into a charging station I'd like know if it's busy or not. And if it's in a busy location and I'm charging, I'd like to know if there is a line up behind me of people who need a charge more urgently than I do. I'll happily let them take the spot. If one doesn't exist, I'd be happy to make one if someone can help me test it.
