I’ll remain skeptical — the satellite view is not vectorized in either platform and the speed difference there is pretty astounding.
Routing is another huge difference — plotting a route from San Francisco to Phoenix takes a whopping minute on MCU1 and only about 5 seconds on the Model 3.
Are you sure the MCU2 sat view is not vectorized? When I sat in a MCU2 car recently and tested it seemed like all text on the map was rotating like vectors and not like the images that have to re-render the street-names, city names etc as soon as you pinch the map around.
