A good example is Morning Edition, which cuts back and forth between the national feed and local reporting.
You'll have 3 minutes of "Korean War Ended", 2 minutes of "Mueller Investigation", then 5 minutes of "Help Minnesota Public Radio pick the best lake in the state - listen to why Mike thinks it's the one he grew up on".
The local stuff is so bad I've mostly stopped listening as well. Wish there was a way to only get the national component.
The local news is one reason I like to stream the local station on TuneIn rather than NPR's various apps. Where else do I hear local news from in this day and age?
