I'm more worried about the fact that the nav info is so outdated that it often thinks the road I'm on doesn't exist and gives me directions as if I'm on a completely different road. How well will that work if I'm on a new expressway and it either thinks it's still the old road, or thinks I'm on a nearby surface street.
Right now this is no issue, because I get to use my own eyes to decide if the road is appropriate or not.
This is removing a feature I find useful, without giving me anything in return. We can argue about various aspects of UI changes before, but those were usually more a compromise, give one thing while taking away another. Adding limits to where AP can be used, if not 100% accurate every single time would not be a compromise, it would be a downgrade.
