Does The First Officer Concur? Shared Control with Smart Vehicle Systems

New computation and sensing capabilities in road vehicles present possibilities for advanced driver assistance systems that can increase safety and efficiency, if the driver will trust them appropriately and use them properly. The two-stage 'trust fall' is a way to study trust in automated systems by testing whether trust established in normal circumstances transfers to trust under extreme circumstances, which will be essential for the successful employment of new automotive systems. Understanding the mental models drivers create of advanced systems, and how they use those mental models to share control with the computer will be crucial to successful design.
