as automation increases, cars will likely become more computers than cars. And at that point I imagine the advances in computation and sensing will drive product refreshes. Even battery tech. Which all sound familiar... Sure some of it can be over-the-air as Tesla has already shown, but the same happens on our current tech yet we still update the hardware pretty frequently. A new, better autopilot may not be able to run on a 3 year old car processor. Could you swap out the cars brains? Sure. Would that be lucrative for the car manufacturer? maybe not. I think the biggest argument against what I'm proposing is that computers/phones have huge form-factor constraints that favor tightly integrated components - it's why RAM is no longer user replaceable in new, thinner macs. Cars, given their physical size, will likely never face that constraint making the modular approach you suggest much more feasible.
