I can understand why they want that, but as a consumer I want a good experience. When non-software companies write software, it seems it is almost invariably inferior. I never actually enjoyed the experience of using a car stereo until I got a deck that supports CarPlay (Apple) and Android Auto (Google). These standards let you attach your phone to the stereo and let the phone run the UI. They are so much better than the software that comes on stereo decks.
Even Apple Maps, made by a good software company, is still noticeably inferior to Google Maps in my opinion. Apple has severely demoted Google Maps on its platform, presumably for the same reason as the carmakers: they don't want to be dependent on Google. So you can't use Google Maps in CarPlay, and if you click on an address in iMessage "Open in Google Maps" is not an option. For Apple I'm sure they see this as being less dependent on Google, but for me as a user it's pushing me away from their platform. I want the best maps product out there, and for me that is Google Maps. So I'm planning for my next phone to be a Google phone.
(It's almost hilarious how far Apple goes in this. If you delete the Apple Maps app from your phone, and then click an address in iMessage, "Open in Google Maps" still isn't an option. But there is an option to re-install Apple Maps. This strikes me as pretty insecure that their maps product can compete on its merits.)
EDIT: I had slightly misunderstood: HERE is an acquisition consisting of all the Navteq data. So it does have legitimately good data behind it.
