When vehicles enter one of these zones, a blue light in the instrument cluster illuminates, and the driver information screen indicates that you are ready and able to take the reins.

BlueCruise uses advanced cameras and radar sensors to adapt to changing road conditions. Ford says it's a Level 2 SAE system similar to some competitors. Autonomously, BlueCruise can negotiate turns on sloping interstate highways and adjust its speed to maintain a constant distance between the vehicle and those in front of it.

Features such as lane change assist will be rolled out at a later date, at which time owners will be able to receive updates via the air. Drivers will command a turn or passing maneuver by simply activating the turn signal. Another luxury, the predictive speed assistant, will launch later and anticipate turns in the road, reducing the vehicle's speed for a smoother, more natural ride.

As additional miles of roadway are approved to become Hands-Free Blue Zones, wireless upgrades will also be offered to owners so they can expand their vehicle's capabilities from their garage.
