The driverless debate: Even in cars that are only semiautonomous, drivers say they'll text, eat and read

Until recently, there was no question about who's responsible for an automobile's operation: the driver. When driverless cars without a steering wheel or brake pedal start hitting the highway, your only role will be ordering the car where to go. Between now and then -- about five years by automakers' estimates -- the relationship between drivers and their cars will enter uncharted territory. Robot-like features will take over an increasing share of the driving duties -- but not all of them. It's by no means clear how well people will adapt during this transitional phase, when human and robots will share the wheel.
