I remember reading that the Model S user interfaces are powered by an nVidia Tegra 3 (Center display), and an nVidia Tegra 2 (Driver's instrument display). Are people finding the computer systems fast and responsive enough? I wonder what Tesla has planned for future cars, because ARM processors continue to evolve rapidly in terms of computing power, configuration, and energy efficiency. Also, I wonder when LTE will become available. Is there a networking module that can be easily replaced? Edit: Ugh, I posted this in the wrong subforum. Can I get it moved to User Interface?
