I think this is the majority of the problem(s) with bluetooth, bad defaults.
In cars, second issue is no button to switch on/off, instead either the overly complex pairing process or the overly aggressive one.
In phones, its non standard playback - I'm in the camp that audio should pause/resume for calls, and calls should always be routed through the phone you use.
If you get a call while on the road either it should do nothing (no connect to car or auto route) or it should be hands free, per phone preference (no fiddling with settings in the car dash, period). This mostly works with some setups, but there's no easy config option and phones don't all have easily customized UIs. Your phone should probably be in charge of the volume too - some car I have gotten into try to rupture my eardrums, others seem to be on whisperquiet and need considerable cranking. Oh, and there should be a BT device priority, there usually isn't and sometimes my headphones get usurped by the car.
My solution so far if I want BT is just to use headphones, and unpair all devices from the dash. I would use in car BT more if they worked in a reliably similar fashion.
A standardized "ask the user" protocol might help some. I don't think Apple or Android play are valid alternatives, though - there are legit use cases for BT interactions that don't involve phones at all, making over complex top heavy proprietary protocols the norm just destandardizes things more, it doesn't make them better.
I don't know how to do this, but drivers should never have access to phone calls. You are driving and should not have that distraction. I've never seen someone drive safely and talk on the phone at the same time. Many say they are safe while in the phone, but independent observation says they are not.
