It's good in some ways. The telly is a massive, communal screen that everyone knows how to use and knows the social conventions around it. A PDF is a common format and useful enough to most people for sharing information. The car thing simply reads what was last "playing" on my phone, which connects automatically through Bluetooth.
But it's all happening by accident. Or as a workaround. Bits of technology that talk to each other, but weren't meant to talk to each other in this way. And the UI is terrible. You can fight your way through it, but it makes little sense unless you know the tech behind it.
It's certainly not explaining itself like good UI should. And I can't help thinking it should just be html in a browser. A missed opportunity.
