> The biggest change I would make to the Model 3 design is ditching the frameless windows and using normal door frames which are less complex (no need for the window to move each time you open a door) and easier to seal up. It'd be interesting to understand why the window needs to move down to open the door. I had a 90's acura integra that also had frameless windows, and the door seal was engineered such that it flexed enough to allow you to open/close the door with the window all the way up, but (as far as I can remember) road noise and weather sealing wasn't a problem.
