Lol my dad does this exact thing I thought it was only him. I actually think it makes sense, since it is easier to shovel when there is less snow less snow than when it all builds up and there is a ton of snow. However if you're going to do that you need to realize that the driveway is just going to get covered up again and again. But without fail my dad will look outside and throw a fit going "oh goddamnit! it looks like I haven't done anything!" Like yeah dad you shoveled in the middle of a snowstorm what did you expect.
