The main barrier is the state of the tech, not media outrage. There is a gap between the current state of the tech, and computers being better at driving than humans, that may be impossible to bridge. In order to bridge it, as a society we would need to accept a period where these things start to become more common, but they make our roads less safe. Only through trial-and-error in blood can this technology improve. I don't think we will collectively see it as a worthwhile experiment.
