> If you're out driving on public roads do you really have any expectation of privacy? Expectation of privacy generally comes from taking steps to preserve it. If you put curtains on your windows, any rando can't install a hidden camera in your house to see what's happening behind them. If you don't install curtains on your windows, any rando can stand in the street and see what they see. The government prohibits you from concealing the number plate on your car. They can't reasonably prohibit you from doing the thing that would establish an expectation of privacy and then use the fact that you didn't do it to say that you don't have one.
