A processor-based electronic system for use in a vehicle may be used to automatically control the vehicle's velocity and position to cause the vehicle to automatically merge into a lane on a roadway or to maneuver around a road hazard or obstacle. A message can be transmitted to other vehicles indicating the vehicle is to occupy a future lane position at a future point in time. The vehicle electronic system may receive a message from one or more of the other vehicles in response thereto. One or more of the other vehicles may adjust their position based on the indicated future lane position. The vehicle electronic system may transmit a further message to the one or more of the other vehicles before merging into the lane.
