One that enables the extra features offered by Tesla? Weird, I haven’t been able to find it. They charge a hefty sum for autopilot, I can’t find anyone that’s been able to get it for free. It wouldn’t be unlike what Dodge would do with a 200hp tune, they’d sell it to you, monitor it, and remove it when the subscription expires. They would be more susceptible to that feature being hacked because they suck at software, worse than Tesla.
