Let's hope Apple fixes the map first before integrating that into their autonomous vehicles.
Before anyone accuses me, I work for a hospital and Apple map still shows a house few miles away when I search for the hospital's address. I have attempted to send update tips to Apple many times in the past years but it is still wrong. Oh well!
4 to 5 years from now, I think Apple maps would be pretty good. Google spent many years perfecting their maps. It's not like the early versions were that accurate.
