Music is something people want. It can help people concentrate and stay alert.
Cup holders allow you to have a good place to put your drink without being distracted. They help you keep attention on the road by not spilling your coffee on your lap.
Ads don't help anybody with staying alert or doing any other tasks in the car. They're meant to capture your attention for selling you something.
If ads jolt the driver awake because they're so jarring, doesn't that help with the staying alert thing? Though if the ads cause the driver to go into fits of rage, that's probably negative on the car being driven safely, though that would again help them with the being alert thing.
If driver alertness is the key factor, cars should have inward facing cameras that can detect the drivers eyes so it can play a horrible noise when the driver starts micro-napping. Or ads for nearby hotels. I think Teslas already have such a camera. New revenue stream!

This exists already [1] and is in pretty much every new car in the EU at least.
