That's an interesting question... I don't have the answer, but clearly there are differences in models. For example, S/X having battery heaters vs 3/Y using the motors, dual monitors vs one etc. It's not just about models either, there are country-specific differences... China got some apps that we don't get, it took a while for Canada to get Disney+... More importantly, the training data for autopilot/fsd is very different per country, we don't get it at the same time etc. I wonder if it'S a global training or if they restrict per continent, and in that case what happens if you move a car from one continent to another.
