I normally connect my phone to my car via USB, in order to use navigation, but it generally tries to connect using bluetooth too, and sometimes it plays the sound out of just one side speaker rather than in stereo for no apparent reason. And if my car is on and my phone is not connected using the USB, it continually launches Android Auto no matter how often I shut it down. So I concur with the xkcd, although I think the issue is more the overall OS than bluetooth per se.
