Being able to look up directions via the Maps app on your iPhone is certainly convenient, particularly when you need turn-by-turn guidance to resume heading in the right direction. But sometimes, you may want to research a route ahead of time using the Maps app on your Mac, taking advantage of the larger display to make trip planning easier.
All that research needn't stay on your Mac, though. It's easy to share driving directions from the Maps app on the Mac with your iPhone. That way you can do your trip planning on one Apple device and then share it with the one you'll have with you on the go.
