Its not uncommon to see people jetting around town after a snow storm with a few inches of snow atop their vehicle which invariably flies off and lands on the car traveling behind these knuckleheads. All this happens at speeds of 40-60 mph.
Here are a few pictures of these lazy people.
And just when I think they couldn't be outdone, I saw one with a few inches of snow piled up on the cars hood. I could not fathom how the guy could actually see the road in front of him. I wish I had taken a picture of that but we were moving when I saw him.
