As kids we used to play street hockey down at the end of our block. It was near the bottom of the hill at a curve on another road. We rescued numerous cars from the snow bank on icy winter nights and they often would give us a “tip” - although we never asked for one. (We did come up with the idea that if we poured water on the street we would be able to help even more folks! Never did do it though!!)
Pouring water on the street to make it icier works better in theory than reality.
Or so I’ve heard. ;-)
