Isn't it all a bit late? Apple Maps went from laughing stock to laughing stock.
It did change for a while in some places, but in some cities things just never changed. Where I live things, if anything, got worse. Pubs are in the middle of roads, shopping centres have no shops or cinemas. Laser eye surgery places become cinemas. A lot of businesses are randomly thrown over the map, nowhere near where they actually are. Towns and cities don't exist, it is still a mess, and to be honest that is not going to change any time soon, if ever.
It is quite often good enough to get you to the right area, but rarely where you actually intend to go. Apple have tried to fight too many battles at too many fronts. Maybe it is time to admit it was a big mistake, whilst munching tasty humble pie.
