title: CMMotionActivityManager returning automotive even when device is stationary
body: <p>We are developing a iOS 9.X iPhone and iPad app which tracks user activities. Based on the activities the app will show different screens with some different activity tracking details. The app is not supposed to show anything when the device is stationary.
  We are able to track when the user is in a car and the trip is tracked well. </p>
  
  <p>However we are seeing that even though the user device is stationary and/or the app is in background, motion co-processor is returning the activity as Automotive with medium confidence level. This is creating multiple false tracking being logged. Such activities have very small distance travelled and/or minimum to no difference in Lat/Long values.</p>
  
  <p>How do we ignore/stop these trips from happening? </p>
