At a larger intersection, which pretty much everybody who lives not in the countryside experiences, google maps will say "turn in 100 feet". But you have to turn now, because you cannot turn as you are going through the intersection. You have to get in the left-turn lane.

Why doesn't google realize that impreciseness is precisely what it needs? Just because it can measure your location to the foot doesn't mean it shouldn't have some margin of error in its app.
