Same here. My wife starts her car in our driveway, and my phone connects to it. Which leads to two issues - she has to fiddle with controls to connect to her phone, and then any audio/phone call that I was having at the time is completely lost for me until I can change it back.

And then Bluetooth is just hot garbage in environments with lots of interference - I work at a games studio so we have loads of devkits with controllers lying around, and my pretty expensive Sony Bluetooth headphones stutter like crazy unless my phone is within a foot of them.
