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.

They seem rarer for me with Google maps. Imo I think rerouting is better with google maps as well. If I get an instruction like that I'll ignore it and turn right and Google will pick up a new routing before I get to the next intersection. If I do it with Apple it might ask me to do a u turn after a right turn and still try and make that left. To be fair I don't use apple maps at all anymore but I see it fail horribly whenever my partner uses their phone for navigation. Its missing a bunch of local businesses and restaurants and sometimes looses the GPS lock on the phone too (like assuming you are on the parallel road to the freeway and trying to route you back on rather than correctly assuming you are still on the 5 and didn't teleport onto surface streets)
