Google’s Assistant app for your phone is getting a voice-enabled driving mode, the company announced today at its annual developer conference. The idea is to bring relevant activities front and center. The Driving Mode dashboard features personalized suggestions for navigation, messages, calling and media.

Within driving mode, for example, you can see if you have a dinner reservation and if so, can quickly tap to navigate there via Google Maps. Once you’re in navigation, you can say, “Hey, Google, play some jazz.” If your mom calls, a notification will appear within the Maps app, asking you if you want to answer the phone. You can then simply say “yes” or “no.”
