I haven’t had much trouble with my car freezing—it’s kept in the garage, and if the streets are icy, I can’t get down the steep grade of the driveway to the street out front, so I pretty much stay at home on those rare days when we have icy conditions.
My pickup stays in the driveway, and has had a frosted windshield several times this winter. I doubt the local PD ever worries about this stuff.
