If only we'd work together then the car could have a common bus system and you'd just swap out the control console on the front and choose your level of [stupid, annoying, distracting] graphics and what have you.
There's no competition in these systems because people choose the car and get lumbered with the UI on the console. Kinda like if houses had unique electrical systems and you couldn't change the white-goods.
Cars already have CANBUS as a standard thing so it shouldn't be difficult.
I think the CarPlay/MirrorLink/Android Auto thing is probably a better model though. Make the console dumb and let me connect my upgraded-every-year phone that's far more powerful.
