One of the benefits of being a Tesla customer has been the free access to the company's Supercharger network of fast charging stations. When Tesla announced the Model 3 it removed that benefit from its new entry level EV. Today it also announced that from January none of its new EVs will benefit from free top-ups.
The cost to Tesla of expanding the network to cope with the increasing numbers of vehicles wanting to use them was clearly going to become prohibitive and one of the things that could derail its expansion plans would be a poor level of service at Supercharger sites and more incidents of road rage caused by charger blocking at sites with limited charge points.
For those users buying a high end Tesla the loss of a couple of thousand dollars of free charging isn't likely to prove a problem, especially as it's likely to result in an improved Supercharger experience.
