Gotcha. I appreciate the info and response. If I may indulge my denial/disappointment a bit — do we know with certainty Y upgrade path is not possible (confirmed by SA or engineering) or just based on teardown of X/S HW4? Just trying to figure out what is officially confirmed. I'd be surprised that Tesla would invest in a major retooling/redesign just for HW4. Thanks again.Different physical dimensions, different harness, and Tesla will not allow it. Even if you replace all the modules, harness, and cameras, it would require advanced level hacking for the car to accept the new hardware.
