Typical logic-fail, overly-conservative, sheep-herd, think-of-the-children thinking.
In the absence of cars, no one would die in a car crash. However cars provide a massive overall benefit so we accept the risks.
In the absence of autopilot, (theoretically, pending more stats) many people would die in accidents that the 'autopilot' is quick enough to avoid and/or limit the severity of. 'Autopilot' (potentially) provides overall benefit even if it introduces some less severe risks that would not otherwise be present. Additionally, expecting this to be perfect is ridiculous anyway. Human drivers are extremely fallible. It doesn't take much to improve in the crash-and-death sense, not to mention traffic flow situations (compare humans merging 5 lanes to 1 for an accident/construction vs. AI)
Furthermore, the risk here is drivers mis-using a technology to begin with. You can mis-use almost anything. You do so at your own peril despite the eleven-teen billion warnings everywhere.
