I have the Moto Z Force. I migrated all my files from the old phone and have been going over settings for the last couple of days. I noticed the phone didn't detect driving and use driver assist for text messages. Further more it did not appear to respond to voice commands of any kind. I finally found the round muti colored icon named Moto in the app drawer and was able to enable driver assist and train Ok Google or Ok Moto Z to wake up the phone to listen for a voice command. Life is a little better now.
