So the police officer wants people to drive around in a car that is zero degrees and not properly defrosted.
Apparently this law has not been challenged yet in court.
I recall an incident in Fort Worth at the fed building some years ago. Seems they were doing some work in the basement which housed parking. It meant changing the traffic flow so one had to enter the exit ramp. Some federal rent a cop was sitting behind a pillar and as cars came in down the entry ramp which was marked closed, he would ticket them. That went on till he ticketed some fed judge who asked what the hell he was doing and why he was not just directing traffic down the correct ramp rather than playing undercover cop. The judge called the fed supervisor of the cop and told him about his concerns adding I will void those tickets as ridicules. I howled when I heard that story.
I believe he simply wants the car locked! However, break the window, and again, the car gets stolen with the keys in the ignition.
