why is this even a thing?
you want to root an appliance that is meant to keep you safe going from point A to point B. Everybody's already concern about outside hacking a car, this is like the worst idea evar!! Other than that you have a dead car with a good MCU and you you're able to charge it via solar for free, and you can park in your garage and run it 24/7.
