SuperCharging seems to be the play to build up some lock in. Not sure how successful it will be, but I can definitely see it encouraging repeat purchases
I would disagree. Tesla's Supercharger originated years before the industry settled on the CCS Connectors and well before CCS Combo connectors came about. At it's inception it was technically superior to anything available.
When the EU settled on Combo 2, Tesla started shipping Model 3s with it as well as updating Superchargers.
The US market is a very different environment than Europe and still hasn't adopted a common standard. The 2020 Nissan Leaf ships with J1772 and CHAdeMO options which are incompatible with the CCS Combo 1 other automakers are shipping. That means a charging station needs to have at least 2 different connectors, 3 if it wants to offer the fastest possible charging because while J1772 chargers are compatible with CCS equipped cars, CCS Chargers are not backward compatible with J1772 vehicles.
Tesla owners are not locked into Superchargers and are able to charge at other chargers via adapters. All Teslas in the US come with a J1772 adapter, and you can purchase a CHAdeMO adapter.
Superchargers are also generally located along highways to facilitate long road trips, something most other EVs are incapable of even if the infrastructure existed.
Tesla sold more EVs in the US in 2019 than all other auto manufacturers combined. The next two best selling EVs (Leaf and Bolt) don't even share a common connector. Building out a charging network that's compatible with other EVs would only serve to benefit their competition. As it stands the Supercharger is a nonbinding value add for any Tesla owner.
