1. A method, comprising:
- while piloting a vehicle by adaptive cruise control;
determining a lane change maneuver based on the adaptive cruise control and determined traffic in an adjacent lane; and
displaying a prompt to an occupant based on the lane change maneuver, including displaying a safe field of travel based on an available lateral acceleration, wherein the available lateral acceleration is a function of a coefficient of friction and a longitudinal acceleration, and the safe field of travel is further based on factors including an intended lane change distance and a lane change maneuver time.
