What I don't understand is why to charge extra cost for the total glass configuration...
One of the reasons to choose the whole glass roof is to improve manufacturability, thus, reducing cost.
Isn't the metal roof going to cost them more than the all glass roof?
Of course if they're able to get extra money from the customers...
An all glass roof at the base price (and therefore no metal option) would be amazing but with Tesla trying to cost save and downsell the Model 3 I think it'll be an option...
