Title. Pisses me off mildly. I’ve got my earbud in for a reason (quick drive) and Bluetooth decides to connect to the car when it starts. The cars’ head unit takes forever to start and have to manually switch over to Bluetooth mode (while the audio is already playing) and the volume is way down.
And when you get out of the car it doesn’t automatically connect back to the earbuds.
I’ve got a slightly different version of this problem. I work from home, and if my wife drives my car out of or into the driveway while I’m on a call, even if I’m in my office in the basement, my phone will disconnect my earbuds and route my audio to my car.
