I suspect it is about the connectors, the charging protocol, and the billing protocol. The experience should be: 1. drive up to charger 2. plug in car 3. car identifies itself 4. charger identifies how the charging process will be funded 5. if there are funds, the charger charges the car and deducts the funds 6. operator unplugs car and drives away. There's a big moat around the supercharger network because it is so big -- but anyone else is welcome to invest billions of dollars and create the same thing.
