"As Apple explains, the M7 can tell when an iPhone 5s user is in a moving vehicle. With this knowledge, the iPhone 5s will not try to join WiFi networks that come up around your car (which will save battery life). An even more helpful feature is that Maps will be able to automatically transition from driving directions to walking directions as you leave your car. While this functionality is interesting, we’re told that Apple is working on further enhancements for the future.iPhone’s M7 motion processor to integrate with Maps as Apple develops indoor mapping, public transit | 9to5Mac
Sources say that Apple is testing a tool for its Maps app that, with the M7 chip, could analyze when your car is parked. When you park your car, the iPhone will register the car’s location. Now when you return to the parking lot, your iPhone will be able to help you assist with finding your car since it knows the vehicle’s location."
