I have a hard time gauging improvements for the broader US since I wasn't in the same location for long enough to see changes. I can tell lots of work has been going on with the Austin data, both in fixes to locations, and extensions of the flyover coverage. And as stated earlier, I stopped running into the major issues with maps being misleading in the later part of the trip.

The one incident that many failed at was my uncle's place (including the mapping solution on "most smartphones"). The road he lives on was renamed and the houses were renumbered 7 years ago. The newer Nokia Now maps and Bing maps gets it right. Apple, Google, TomTom, and Waze all stumbled. Made for quite the adventure to find him.
