It's clearly a sign of the times house much things have changed, when people are far too worried about being sued than actually clearing their driveways and paths.
When I was clearing off my parents drive over Xmas, both my Grandfather and Parents can remember how when it used to snow years ago, all the men who lived on a road would come together to clear it all. The wives would all make tea and snacks for them.
In a lot of cases, you have to clear your driveway if you need to use your car(s), and in the current conditions, you can't just wait for it to melt, as it's only getting harder the longer you leave it after it falls.
When I lived in Canada a few years back, in the winter if you didn't clear your driveway, you wouldn't even be able to your bins emptied. The longer you put off doing it, the more snow that builds up and the more work you have to do to clear it.
