In most new vehicles, there is a convenient compartment for storing your sunglasses, located on the ceiling just above the rear view mirror. Due to the giant windshield, no such compartment exists on a Model X. I wear prescription glasses, and have prescription sunglasses, and I switch between them when getting in and out of the car. Where is the best place to keep your glasses in an X? I'm always concerned about them getting tossed around, scratched, or lost if they are not in a consistent and secure location.
