I am finding this more and more common place on my commute. I chalk it up to the Bluetooth headphone push/ loss of the aux. People either don't have headphones now or their Bluetooth ones are dead. I just resort to putting my headphones in, maybe make a bit of a show of it in hopes that they see me.
They are all unchecked by default but you can't save and exit, it just loops back to the subscribe screen.
