Google Play Services has access to my car speed Digging around in my Note 4 settings and discovered under location that the Google Play Services has access to my car speed?    Really???  Why would Google need to know how fast I drive??  What if any functionality would I lose by force stopping the service?    Is this specific to Samsung and the Note 4?  Or a general setting for all Google users?                                     Curious
Access to your car's speed seems like a new permission added for Android Auto.
The fact Google Play Services has that permission allows it to act as a common provider for this information to other apps (apart from using it for analytics).
