When that stuff dislodges on the highway it’s not like your car getting hit by a snowball. It’s like having an entire wheelbarrow full of snow hit your car all at once at 50+ mph. Just the weight of it can KO your entire windshield. It’s a super effective way to make someone crash.
Also, it’s not always just snow. If the snow on your vehicle sat there through a couple of freeze/thaw cycles, there can be a big sheet of ice underneath. If that goes through someone’s windshield it can kill them directly. If you live in a snowy place, pretty much everyone you know has a story about the time they almost died because some asshole was too lazy to clean off the roof of their SUV, or because a huge sheet of ice flew off the top of a semi-trailer.
So they’re saving time.
Any negatives?
I guess it might be annoying to drive behind someone with a roof full of snow falling on your windshield.
Yeah. You can kill people.
