Why do you think they are lazy? You have no idea about them and are making snap judgments.
It's the very definition of lazy.
Too lazy to have it cleared off.
Too lazy to have/get an ice scrapper.
How else would you define it?
The state police around here pull people over all the time for not clearing snow off their car. I did see one where it was all covered on the roof and the rear window, just a bit of the front was cleared off.
