For instance, just now I pulled up directions to the place I drove on Sunday. Apple Maps gives three routes, ranging from 35-40 minutes. Google Maps gives three routes, ranging from 29-33 minutes. In my experience, it will take closer to the time Google says, so if I'm using Apple Maps, the ETA will start out at 35 minute from now, and by the time I get there, it will be 5 minutes sooner. The only "current condition" it is depending on is that I'm driving faster over the route than it expects.
