I am surprised not to see more conversation on Tesla Glass? I see a lot about a possible HUD, but my understanding of Tesla Glass is that it will be a solar glass roof that can charge the battery from the sun. If so, while driving during the day, sitting in a parking lot, the battery could be charging. The rumors are that Model 3 will have this as at least an option. IMO this could be a much bigger feature than a HUD. Am I mistaken on this?
