With the price difference between a Model 3 and a regular car, you could install an entire theater room system with absolutely top-of-the-line sound quality and power, a cutting-edge HDR projector (or a big OLED TV) which would absolutely put to shame anything the Model 3 can do as a theater experience. I think it’s cool that Tesla is finding new ways of getting value out of their cars, but to answer your question: Many people would prefer a proper theater or music experience. Also, while Tesla’s sound quality is among the best out there for cars, no car audio can hold a candle to the music (or theater) sound quality you can get from large high-quality speakers (far too large to fit in any car) in a well-damped room (with acoustic treatments if necessary, e.g. if you have hard floors or too many windows). You could install the best speakers in the world in a car, but it would still sound worse than in an average house due to all the acoustically reflective surfaces at many angles (e.g. glass) and oddly shaped compartment which distorts the sound in ways that cannot be perfectly corrected even with DSP.
