I still use headphone jacks on my phone, I wouldn't buy one without it. It is just more garbage to manage and more stuff to fix when it doesn't work. It takes half a second to plug in a cable and I don't gotta run around broadcasting a bluetooth signal which drains battery when not in use and takes as long to disable as pulling out a plug. Plus it is often lower quality than the cord.

Bluetoothing to your car is to me the same energy as using "wireless" charging stands for your phone. You are just replacing a physical tether with a less efficient digital tether of higher complexity for no actual gains.
