The worst part about Google maps while driving is that it won't read directions until your right up on the turn.
Also, it's forking is completely fucked. If there are 2 right turns coming up it does not indicate which lane I should be in. In once case I had to drive 60kms, 30 kms there and back, because the interchange had 3 right exits and I chose wrong.
Now I use Google Maps to find the location and copy the coordinates into Apple Maps. Or use Waze.
My big complaint is that Google maps announces I'm on the fastest route even when I know I'm not!
