Several studies have shown that older drivers are to a large extent willing to consider using and buying ADAS such as reversing aids and collision warning systems that are aimed at the prevention of crashes on intersections (Oxley and Mitchell 1995; Viborg 1999). Furthermore, older drivers are also willing to accept systems that give feedback messages or that (partly) take over vehicle control, like automatic speed or distance adjustment (Viborg 1999). The drivers should also be able to understand the information the ADAS sends, via a display, by sound, or haptic. Older drivers are also more susceptible to poorly defined ADAS than younger drivers.
