Why do people think crowd sourcing is magic?
Crowd sourcing is a minority source of map data. Even Google Maps gets what, maybe 10% of it's map data from crowd sourcing? And it's starting off with better data and more incentive to correct mistakes as they affect the business listings in the world's biggest search engine too.
When you combine that with the fact that the crowd sourcing on Apple Maps *sucks* (data updating seems to be very slow, the inferface to do so when a POI is missing is terrible, the interface to do so when the actual map itself is wrong is non-existant etc etc), Apple Maps is not going to get better quickly. Anyone who thinks so is living in complete denial.
