Agreed, we don't need "show all level of details" when that's not tenable. I'd just prefer Google Maps to be a bit more "dense" when deciding what zoom level to show details at. This is particularly a problem with maps locations-- it's far too easy to get the incorrect impression that a building you are looking at is entirely a Denny's when in reality it's a strip mall with 5 businesses if you zoom in a little closer...
