Google Maps is not that great in places they don’t prioritize. They have no ability to handle tolls and direction of roads that are based on day of the week and hour. Local examples from the DC Area: I-66 is marked as a toll road 100% of the time despite only being tolled at rush hour in one direction; Clara Barton parkway is always marked as two way, but it becomes one way during rush hour, I regularly am routed down it by Google maps when it is one way the opposite direction.

I frequently am sent down nonexistent roads in rural Massachusetts, meanwhile there is a paved road in Bristol, NH that Google refuses to route people on; it is used by Apple Maps.
