How is this not illegal?

How is having a custom black Miami heat license plate + a smoke black license plate cover over it and pitch black tints on a car not illegal? 😂 dude gave me an attitude because he was backing up into me and I honked my horn at him so he wouldn't hit my car, then he had the green turn arrow and he stood still until it turned yellow so I honked at him agian and he tried to follow me where I was going until I turned into a gated area with security at the entrance 😂
