I disagree, Android Auto and Apple CarPlay are great. The problem comes when the manufacturer’s interface collides with the Android / Apple interface. Just build a great touchscreen, let Android / Apple handle everything they can, and leave the rest (HVAC controls, volume controls) as physical buttons and switches. You get the best of both worlds - no need to pay an in house team of software engineers who will never be able to compete with Google or Apple anyway, and you please your customers who by and large want physical buttons and knobs.
