I want my phone to still be reachable. I want to receive texts still, as well as calls. I just don't want to be inundated with interrupting notifications while trying to listen to something when I can't easily manipulate my phone.

They could make an optional setting to where after a notification pings, your phone won't ping for subsequent notifications for some time frame after, like, say, 30 seconds. They could also let you set default notification preferences when your phone is connected to Bluetooth in a car or playing continuous audio streams like music, audiobooks and podcasts. Like if I'm in a vehicle with a screen that has popup notifications, maybe that's the only way I want those notifications while in the car. Or maybe while listening to audiobooks, music, or whatever, I may want the notifications to not pause the audio, but play concurrently, or only vibrate instead, or flash my phones flashlight, etc.

There should be other options between accept constant interruptions or cut off all contract from the outside world.
