I've long wondered why no car manufacturer has gone for an open source model. Certain things should absolutely be locked down (for example, the airbags and other critical safety features) but there is absolutely no reason the HVAC and Infotainment system need to be closed source. Open it up and let hackers go crazy, then just "borrow" the best options out there for next year's model and everyone wins!
