MICHAEL WALSH: A Nation Of Passengers. “There are more sinister reasons to be wary of driverless cars, however. In the post-9/11 age, the government has a limitless appetite for surveillance power—law enforcement is now able to track every American carrying a cell phone—a robocar is a “convenience” just waiting to be exploited and abused. Who, for example, programs the ride? Who controls it? Should the police decide that they have a few questions for you, what’s to prevent your Johnny Cab from detouring from grandma’s house to the local precinct station? And if it does, what are you going to do about it? These are not idle questions.”
