Things like Apple Maps are a special case, where improvement is driven by public exposure. Yes, Apple’s maps were full of errors upon initial release, but improvement was fairly rapid (albeit entirely opaque, unlike a typical open source project).

Today, I find that while Waze does the best driving navigation and Google Maps is unbeatable as a modern yellow pages, Apple Maps is equal to or superior in nearly every other way. It’s walking and public transport modes are, in my experience, consistently superior to anything else.
