I took delivery of my Model X yesterday afternoon. This morning, while driving home with my family from the library, a cop pulled me over. He could not see the temporary registration through the tint of the rear window. He told me I needed to take it down, get it laminated, and mount it where the real license plate goes. He also said the rear windows were tinted way below 20, and while he doesn't care, a "statey" could pull me over and write me up for that. He let me go on my way after verifying that I am the owner of the vehicle. My X is unmodified, with windows exactly as delivered from the factory. What is the tint from the factory? Is it below really 20? Has anyone had any law enforcement issues with the default window tint or the temporary tags? Did you bother mounting the temp tags on the exterior?
