Tesla's Supercharger network was originally designed to enable long-range trips and offer a viable charging option for people who can't usually top up at home or the office. They've quickly become all-purpose stations, however, which can be a pain when it leads to overcrowding and abuse. And Tesla has had enough. As of December 15th, it has implemented a new Supercharger Fair Use policy that discourages commercial EV drivers from topping up, whether they're ridesharing or delivering goods. Tesla's not banning use as such, but it might ask you to "modify your behavior" and has warned that it might limit or even block Supercharger access to ensure that chargers are open for personal use.
