I drive an older car with an old fashioned CD player rather than an infotainment system so what do I do? That's right. I put my phone in a cradle next to the steering wheel and use Spotify.
Apart from the serious issues caused by the lack of tactile feedback and the fact you have to look at the interface to use it, it's like the Spotify product development teams have gone out of their way to make the app clumsy and dangerous to use whilst driving. It is crappy and unresponsive, with way too much clutter.
I swear, Spotify have a giant engineering team and I have literally no idea what they spend their time doing: it's certainly nothing that I find useful or that improves my experience.
So in order to avoid dying or killing anybody else I plug the phone in to the aux socket on the car stereo (no Bluetooth in my car), select a playlist before I set off, and then let it do its thing. I'd switch back to CDs but they're a pain in the ass to carry in bulk. Or I listen to an audiobook.
I hate touch interfaces in cars.
