I just gently (like without pushing down--just the weight of the brush itself) brush snow off the car's body. No need to get every flake, just the bulk of it so that it doesn't impede your vision/blow off and impede visibility for other drivers. Driving your car with snow piled up, you risk letting the snow slide into your vision, and risk the snow blowing off into other cars. Like someone said, it's a daily driver. I wouldn't scrape icy layers off like I do for the glass parts, though.
