I reported an issue to Google where they were routing traffic off a highway and down a two-track road that basically ends in the middle if you don't have a 4x4 truck, then back onto the highway at the next intersection. It took almost five years for Google to change their mapping directions to keep people on the highway. I got the county road commission to put up a sign saying the road was a dead end quicker than I got Google to change the map.

An anecdote, I know, but I'm just saying Google has these problems too. It's not just Apple.
