Obscuring license plate might be prohibited by law, but so far I been pulled over twice for not having license plate AT ALL. Twice got ticket to show up at court, twice case was dismissed because cop did not show up.

I don't think there is law for not having a license plate. License plate are only required in case you commit a crime or break the law using your vehicle so identifying you is required. I was ready to argue in the court that I should be presumed innocent when it comes to driving my car, just like walking on the street I m presumed innocent and do not have to have my state ID plastered to my forehead, in case. I'm currently awaiting to be pulled over for the third time.
