Yup, it be like that in snowy places. As a finnish person, I'll also endorse the message: Brush the cars rooftop of snow too! Its not fun to end up in the same situation as the author and panic when you don't see shit from the snow that slid from the roof. Then you have to brush the car again and could be jamming traffic if you can't park safely with the snow on.
Its a drag in the winter, as is getting in a cold car in the morning if you don't have a heater either in the car or separately bought. And driving during a hail is dangerous, especially if in an area without lot of light, its like driving in pure darkness sometimes. Which is why I try to time my traveling to happen during the maybe 6 hours of light during the day.
...at least we get to admire pure white landscapes and those rare nice days when sun's light makes the snow glimmer, like you are standing in a field of diamonds
