In Android Automotive 14 release notes there is one item:
Heads-up notifications (HUN) throttling and suppression. Developed an OEM-configurable mechanism to prevent the overlapping on HUNs and the sending of HUNs to drivers at inopportune times.
But what exactly is that mechanism? Where I can see the logic of it, some related code maybe?
I looked at https://developer.android.com/training/cars/notifications and https://source.android.com/docs/automotive/hmi/notifications/hun but can't find anything about throttling and suppression there
