> This makes sense: presumably there's no good way to talk to the built-in system; having a second system running that can't coordinate with the self-driving system would likely make the combined system less safe. Even if communication between the two were possible, I'd still imagine that just having a single system operating the care would be much more desirable. That's the exact argument I make for never buying a car with that technology because I'm driving it and I have no way to communicate with it... I'd be super happy to be driven around in an autonomous car, but have zero interest in auto-lane-keeping-pilot-collision avoidance-parking etc
