As I think someone's pointed out already, it gets like a skating rink when you don't do it properly.

Properly involves shovelling it, then sweeping away any remaining slush/water (doesn't add much time to the process), and then salting the cleared patch

If everyone did that, we'd be fine.

Compacted uncleared snow is fine until you get a partial melt which refreezes as ice, or a new fall after an overnight freeze which covers any icy patches so that you can't see where they are. Then it's a skating rink anyway. If it was cleared and salted first, this is less of an issue.

And yes, that's from someone who actually does it.
