Think about it a bit more. You still need wires for power, you can’t be swapping batteries in car accessories as you can in your home. If you are already running wires for power, running 1-2 more for data is not that problematic, you are already running the harness. In addition, you don’t want the latency and unreliability of wireless solutions in a car. It might be ok in your home, but not in a pretty rough environment such as your car. It would also be much more expensive both hardware and software wise, not even mentioning the potential bugs and such.

It has a ripple effect for other parts.
Button for everybody: More expensive and can't be sold as a package
Button optional: No Button -> Hole in plastic molded cover -> Either need different molds/parts or an additional preparation step removing the plastic covering the hole. Car manufacturing is traditionally very low margin business and extremely streamlined. Sooner or later EVs will also end up in the same situation
