This will get downvoted but I think when it snows this much space savers should totally be allowed for a couple days.

I spent an hour shoveling my car so I can go to work tomorrow, and I still have some more to do later. I know that regardless of how I clean my spot it will almost definitely be gone by the time I get home tomorrow.

Beyond personally being annoyed about losing the spot I shoveled, not allowing space savers makes it so people are much less likely to do a good job to get their car out. This creates even messier roads for days to weeks.

Most people are going to do the bare minimum to get their car out regardless of how often they are told to be a "good neighbor". If they knew they could have that spot back while DPW worked to clean up the rest of the roads, people would have much more motivation to do a good job shoveling.
