The current Leaf is a few years old now, I would assume and hope the upcoming Leaf will have it.
I would’ve agreed with you until I used CarPlay. Bluetooth streaming in most cars is just terrible, nobody implements the standards correctly and in a nice user friendly way. CarPlay, while you do have to plug in a cable, hands it all off to the phone, and as long as the apps are written properly, works pretty well. Apple Music works well, with good voice controls, and I’m lazy and just throw everything into one big playlist for the car that I shuffle. Pocket Casts is good too.
For shorter trips and where I don’t need navigation I stick with DAB though, which serves me well.
