A score is generated 420 for a requested vehicle lane change 405 and vehicle components (e.g. steering actuator) are actuated to perform the lane change 440 upon determining 425 that the score is less than a predetermined threshold within the predetermined time (Fig.3A). The request may be made by a user input and the score may be periodically determined during the predetermined time. The score may be based on a road curvature, a traffic restriction or the detection of other vehicles. It may be a value (e.g. a number or percentage) indicating a risk of collision during the lane change and may be indicated by low, medium, high or imminent risk. The requested lane change may be prevented 430 upon determining that the score exceeded the threshold during the predetermined time (Fig.3B) and a further user request may be ignored 410 for an inhibit time thereafter. The vehicle may operate autonomously.
