What about Tesla iD?
Possibility 1 - Tesla's appstore, gives your Tesla displays a custom look, apps that suit you, etc.
Possibility 2 - New name for the Model 3. Mass market car, people want to be unique. Lots of colors, wheels, options...car, wagon, SUV, roadster, etc. Give your car your own personal "iD"
I know it's a stretch, just trying to guess something different from everyone else!
- The Beta will be on display and you guys invited will get to see it up close...maybe even get to drive one!
