Garages are expensive to build and if you design your roads so that no person with the means would choose anything but driving and ignore the rest, then sprawl becomes the reasonable choice, since people are driving to every destination anyway. What's the point of the added expense of a garage if you don't really care about being close to other things nearby?

Haven't tried that, but Organic Maps is another OSM based app that has a pretty clean UI

If you want to help make OSM better, there are a few apps that make it really easy to add details to your local area.

Street Complete has gamified quests to add details to things, including hours to shops.

Every Door is a step more detailed, but makes it really easy to add new things to the map.

Organic Maps is a nice Google maps competitor that does make it easy to make edits while in it.

Also, if you use maps in any other app, like bike share or fitness tracking, they probably use OSM data, so it can be worth making improvements where you can since it'll make those services better too.
