I often choose to use apple maps for nav. One annoyance is I will chose a preferred route out of the options it provides --that's good. Then, for no reason, Apple Maps decide mid-course somewhere that I must have actually wanted the other option I did not choose and it tries to re-route me. This happens from time to time, not too frequently, but enough to be annoying.

This often happens when differently-named or -numbered roads join end-on (i.e. one road becomes the other as you drive along it), and Apple Maps does it too sometimes.

Yeah I do get that. However, it used to not behave this way. So I can't help but think they broke something in recent years. I think they just wanted to increase the frequency of updates probably for "engagement" since tech companies generally go with quantity over quality on notifications. But this just breaks the functionality for me.

I forgot to mention sometimes "Continue straight for 1 mile" causes me to begin my migration from left lane to right lane in anticipation of the exit, then she just says, "Continue straight for 3 miles" and I'm livid. (Not sure if this is widely understandable but I tend to speed and usually am in the left lane passing/speeding, while exits are generally on the right so I interpret "Continue straight for 1 mile" as I have an exit coming up).

That impacts me with Apple Maps on occasion: if there’s some road name/id change that is effectively invisible as a driver because I’m still going straight, or more annoyingly when there are roundabouts in my path.
