Just curious. What's the incentive for Tesla to ever release these adapters? All they will do is let people that now are having to pay Tesla for charging move to Tesla's competitors. Some anti-trust fans might call it tying.
It allows the cars to be used in areas that Tesla can't/doesn't want to support. They have stated that the Supercharger network is not priced to be an income/profit stream, so it would be more why wouldn't Tesla want to create the adapters to reduce the demand on their network and reduce their costs?
