For the longest time Tesla did not have any info about the shared Supercharger stalls. Now (not sure when exactly they added it) they have this recommendation Quite frankly I think the whole shared charger concept isn't great but I see, from a technical point of view, how it makes much better use of the resources. But it just sucks when you arrive at a Supercharger. The labels are usually hard to read from within a car, especially at night. When some stalls are taken, those labels are hidden by the cars. Many times half or more are taken, so now it's a pure gable to find the stall that is paired with the car that has the highest charge level, thus offering the highest charge rate out of all. Here is an idea how to fix the problem: I really wish Tesla would have a colored LED light on all stalls similar to a traffic light. Green = not shared, full power available Yellow = shared, but more than 60 kW available Red = shared and less than 60 kW available With such a simple color code on top of each stall, you can very quickly locate the stall that gives you the best charge rate.
