Actually, I wish people around here would get tickets for snow covered plates. It pisses me off that people can't take 2 seconds to wipe the damn thing off.
You got these jerks in 4x4's driving like maniacs in a foot of snow. What if they hit a car or run one off the road? The driver of the car is the one who's screwed because they have nothing more than a description of the truck, at best. This past winter here was the worst in many years, and I can't count how many close calls I saw. And almost nobody in a pickup wiped the snow off their plate.
If you have a 4x4 in a foot of snow with essentially no license plate - you can literally get away with murder. Who's going to catch up to you?
Keeping the plate unobstructed is no joke.
