This document describes the results of survey research undertaken by the Automobile Club of Southern California. Questionnaires (10,000) were mailed to insurance customers who own vehicles that may have adaptive cruise control (ACC) as standard or optional original equipment. Half of the questionnaires were mailed to vehicle owners who were younger than 65, and half of the questionnaires were mailed to owners who were 65 or older. Of the 1,659 questionnaires returned, 370 were from ACC owners. Follow-up telephone interviews were conducted with 17 ACC owners. Survey items addressed topics such as learning to use the system, behavioral adaptation, system effectiveness, and perceived safety of the system. Although most ACC owners would want to get their system again, many (72%) were not aware of manufacturers' warnings about system limitations. Some differences in responses between younger and older respondents were noted. Other response differences were related to vehicle manufacturer and experience with the vehicle (miles driven). |
