I use Waze to give me traffic alerts and alternate routes on the to work and home. In order to do that I have to turn on navigation, but I already know how to get to work and home. If Waze had a commuter mode it could learn my preferred route to and from work, then in lieu of turning on navigation, Waze would know my destination and give me traffic alerts and alternate routes without having to turn on navigation, and I could leave the audio on.
