By Ben Klayman DETROIT (Reuters) – Ford Motor Co Executive Chairman Bill Ford said new technologies that allow cars to talk to each other and drive themselves may scare some people, so the industry will need to allow consumers to opt out of such features. A lot of this really cool technology … kind of freaks some people out, he said on Monday at an intelligent transportation conference here. Some people hear autonomous driving, and say Oh my God, I never want to get into that vehicle, he added, referring to self-driving technology. We believe, at Ford, that opting in is important so people do have that comfort.” Automakers are racing to develop such features as cars that apply brakes automatically when they sense an impending collision or slow down because a vehicle ahead on the highway has warned that traffic has stopped.
