I do this all the time, especially while driving. I plug an aux cord into my phone to listen to podcasts or audiobooks and plug the usb connection into power supply in my car. I wouldn't be able to do a long road trip if I had to switch between these.

This is a decent amount of people but I think this is increasingly rare as more and more cars have Bluetooth. And it's not hard to update many older cars to newer headunits that have Bluetooth in them. (as I did for some of my cars) or just get a headunit that does power+transmission over USB too.

You can definitely tell the difference between bluetooth and an aux cord. There's no excuse for using a wireless connection between a phone and a car that are already plugged into each other anyway

Personally, I dislike having to plug in multiple cords. 3.5mm also doesn't transmit what you're listening to. I find that pretty useful to know. My phone screen is used for other things besides displaying song info.
