I find Apple maps is very good in this regard and will keep you on the highway even if the traffic is higher and the route longer, because usually over average it's faster. I see a lot of people exiting when they see traffic come on and I can't help but shake my head. We've all tried it before, and it almost never works. The value of Apple maps to me is if there's HUGE traffic - like an accident closing 3 lanes. Often there's no indication of this otherwise, and you can be stuck for a whole nother hour. But Maps knows, and it'll put you on a longer highway to get away from it. I no longer use apple maps in my daily commute (1.5 hours one way). But, when I did, it caught quite a few huge accidents. Now I leave the office earlier and the likelihood of accidents is much lower, so I don't need Maps. Even so, once in a blue moon I'll be in a sticky situation.
