Incoming messages are displayed as notifications that animate down from the top of the screen.
Message notifications should be displayed if:
- They are important enough to interrupt the driver
- They are appropriate for driving
For example, friend request notifications are not appropriate driving interruptions.
The system may limit notifications if there are higher-priority items to show.
