Reached out to someone at tesla. Inquired about tesla enabling third parties to tap into software to enable third party hardware using Tesla UI. Here is response I got. "Well, not really. It is a bit more complicated from what I understand. We are not offering it as an option because the hardware connections (wiring) is not there. Retrofit would require new rear and front harnesses along with front and rear bumpers, park assist controller, vehicle configuration change AND firmware. Also most aftermarket systems would not play nicely with our setup. In short it would be cheaper and much easier for existing owners to source an aftermarket setup rather than retrofit the factory system. "
