The latter I mean. "Take a left on pico from this stop sign, hold your breath and good luck, no one will let you in." Somehow google maps ignores these and prefers me to make a right out of a parking lot or a stop signed street and take my lefts at lights (or off the major arterial) seems like its just a simple set of rules you can apply to your navigation algorithm to avoid these entirely, but the fact that they are still there years later tells me the Apple maps designers really don't care too much.
