My car, despite being a European (actually UK) model, has a Type 1 socket which does lock, just as the manual says it should. Moreover, the US manual for the 2017 model also says that if the door is locked, the connector should not be inserted, I assume they mean car door(s), as the connector door clearly has to be open to insert the connector. It also says that theft of the charging connector may be prevented by locking the door with the smart key or the central locking switch, and to unlock the car door to release the connector after charging.
