Really? I have tons of music ripped from CDs on my iPhone and I can trivially play that in my car. I have CD players in my car (which I never use) and attached to my stereo (which I rarely use). It's not that the ability to play CDs (or rip them and play them) has been diminished but a lot of people prefer to just use a streaming service.
I'll grant that many people don't have a CD player even on their computer any longer but you can buy one for not much money online and have it in a couple days if you want one.
