I have read places that people expect Tesla to start "reserving" specific charger stalls for specific cars as a way to keep that ganged charger issue at bay. If you pull in next to someone who also just pulled in, the two of you will have an hour of charging ahead, but if one of you two went to a different charger where the ganged stall has already charged its car to 45% you will not charge as slow.
This could mean Tesla tracking the cars along a route and suggesting the charger stop that is likely to be less busy by the time you will arrive based on when you start navigating. Sure there are a lot of variables, but most of them are tracked by the car or the routing software like how fast you drive and how busy the route is. Plus the specific stall to pull into could be assigned as you drive off the freeway or even into the parking lot so there is no confusion if someone takes your spot before you arrive.
No more accidentally pulling your 2014 Model S into the v3 charge stall at Kettleman City because you don't know your car's capabilities.
