i remember a court case that was in the pappers here. some guy didnt knock it off his car. he had 6inches of snow and ice and it slid off and hit a kid walking down the street. it cut up his face and head pretty bad. he ended up in the emergancy room.
He was walking too close.

An ice sheet being lifted off a car can get some pretty good hangtime, especially with the turbulence following behind a car. In addition, the sheet will not continue moving forward at 60mph, it will tumble, which will slow it down considerably. I don't know what kind of following distances everyone here has in mind, but highways would have an awful lot of empty space on them if you stayed back far enough to avoid large flying sheets of ice.
Windshield glass is also not tempered, it's laminated. Tempering glass adds quite a bit of strength to it.
Someone did mention too that ice sheets off of semis can kill people. That's another matter entirely, because there isn't any good way (yet) of easily and cheaply removing ice from the top of a trailer.
Now, if I've only got a light dusting of fluffy snow, I won't bother clearing anything except the lights and rear window. The windshield wipers can get the front, and the wind takes care of the rest. If it's a few inches of fluffy or powdery snow, brushing it off takes less than two minutes.
If the car's completely iced up, it'll probably take a screwdriver just to get one of the damn doors open. Then I scrape off what I can and head out, or else decide that I'm not going to go driving anywhere that day.
