I always make a point of clearing the snow off before I set off. Often I see people with a huge wad of snow on their roof, and a little clear space where they've shifted it from the windscreen.

You just know that the first time they hit the brakes it's all going to end up over the windscreen.

I was also overtaking a lorry last week when huge sheets of ice decided to detach themselves from the top of it and came crashing down onto the road, a la Severn Bridge (not the driver's fault - he wouldn't have been able to get up there to shift it).

Fortunately none of it hit my car, but it was a bit scary.
