I used to be in the space. Basically everyone would install an SBC behind the dash to listen to the canbus and then report things over cell often with ways of shorting a circuit in order to do features.

It's whackadoodle. I mean how different are cars, really? They have wheels, doors, windows, odometers, go places at various speeds, need fuel ... you'd think there'd be some agreed universal baseline like MIDI ... you'd think.

And the manufacturers held on to their protocols like they had done their own Manhatten project so everyone just had to backwards engineer things.

Why is inoperability so precious? Ultimately the purchasing decision is the car's price, features, availability, terms of the deal... The phone app has nothing to do with it, let it go.
