My LRDM delivery is still a few weeks (maybe months) away. For those of you who have your Model 3s, I'd like to get your thoughts on screen protectors. Is there a real concern of scratching your screen without one? Is it useful for other reasons, reduces fingerprints, glare... the likelihood of cutting yourself on it if you get in an accident? Does it affect the touch screen responsiveness? Which ones have you used and liked, not liked? Any feedback would be greatly appreciated. Thanks!
