Just reading the original quoted mid article without the extra commentary it's clear the story is unrelated to listening to the radio in itself and to do with the camera mechanism monitoring for other forms of distracted driving not being able to tell the difference:

Still a shitty system by all counts... but a lot easier to talk about it directly than via rehashes.
