So this seems like a pretty obvious question, but I couldn't find any threads to answer it: Is the Model 3 screen made of glass or plastic? I'd hope for a car in this class it is glass, but I don't want to assume. I've always had an iPhone which has a glass screen, and aside from the eventual minor barely noticeable scratches, it's withstood the test of time. Trying to decide on whether I need to invest in a screen protector or not. (If it's glass I'm pretty comfortable leaving it as is and giving it the occasional wipe down; if it's plastic, I need to start shopping!). Thanks!
