Bad Weather or Bad Drivers?

I have been appalled the past couple of days at the absolutely abysmal level of driving ability I have witnessed on out roads. I suppose too I would have to say there has been a great deal of stupidity.
Here are some of the things I have seen:-

People who have only cleared a small area on their front windscreen - how can you see to drive if your side windows are covered in snow and ice? Isn't this dangerous driving or at the very least driving without due care?

People who do not clear the snow from their lights - what is the point of having them on if no one can see them because they are covered with snow?

People who are frightened of driving in the snow and as a consequence drive at around two miles an hour - this is partly responsible for some of the hold ups, especially on roads that have been well gritted and are reasonably normal, and  could lead other drivers to take risks overtaking them out of sheer frustration.

People who get stuck and then stick the car in first gear and hit the accelerator pedal causing their wheels to spin - second gear and low revs is far better, remember the tortoise and the hare (slow and steady wins the race).

People walking in the road to avoid falling on footpaths - what happens if a car hits a patch of ice and loses control? I would rather risk falling on the footpath than being hit by a car!!

People walking in the road and pushing babies in buggies - words fail me.
