If I miss something important because the directions seemed correct overall but were in fact wrong, then not only do I get emotionally hurt, there could be real life damages. Not just missing a meeting or lunch date but imagine being late for your immigration interview or being delayed when visiting a hospital during a loved one's emergency. Sure, you can blame me for not being prepared enough but I TRUST my Google Maps app. I can't recall the last time Google Maps was severely wrong. The worst I've gotten is being directed to the non-public entrance of a gated community when visiting a friend.
I want to trust the iPhone's new Maps app too but I can't yet. So it's not a small "oopsie one wrong turn" issue. Missing an exit around where I live can be a 40 minute detour. If a software upgrade causes me to be late for a once-in-a-lifetime job interview, the least I expect from the CEO is to admit that their software sucks.
