Summary
This study investigates the acceptance of in-vehicle safety systems among older drivers and evaluates how these technologies might influence driving safety and habits. The research is motivated by the rapid growth of the older driver population, particularly the aging baby-boomer generation, who may differ from previous generations in their willingness to adopt technology. While older drivers generally have lower crash rates due to self-restrictive driving habits, they are overrepresented in specific crash types, such as intersection collisions and incidents involving other road users, often caused by age-related declines in vision, hearing, cognition, and physical mobility. The study aims to identify which in-vehicle systems best mitigate these aging effects and determine if older drivers will accept them. The methodology combined a comprehensive literature review with qualitative focus group data. Researchers reviewed over 65 peer-reviewed articles to identify age-related impairments and potential technological solutions. They constructed an initial safety rating matrix that categorized systems into four types: sensory enhancement, alerts, vehicle control, and fully automated/connected vehicles. These systems were rated on their ability to counteract specific impairments like vision loss, hearing loss, and slowed reaction times. To assess user acceptance, the researchers conducted six focus groups with 51 drivers aged 55–75, split into two cohorts (55–64 and 65–75). Participants viewed simulator-generated video demonstrations of four specific systems: blind spot detection, intersection navigation, night vision assistance, and forward collision warning. Qualitative data from these discussions were analyzed for themes regarding trust, anxiety, and perceived utility, which were then integrated into a final safety rating matrix. The findings revealed distinct differences in system efficacy and user acceptance. In the final matrix, alert systems (e.g., forward collision warning) received the highest safety ratings, as they effectively counteract multiple age-related deficits. In contrast, vehicle control systems (e.g., anti-lock braking) received the lowest ratings, as they primarily address only reaction time and cognitive decline. Regarding acceptance, the younger cohort (55–64) expressed higher trust in the technologies and believed their peers would desire them, though they also reported greater anxiety about becoming overly reliant on the systems. The older cohort (65–75) was less anxious about reliance but generally less trusting of the technologies. The study concluded that while alert systems offer the greatest potential safety benefit for older drivers, acceptance varies significantly by age subgroup, with younger older drivers showing more enthusiasm but also more concern about dependency.
Key finding
In-vehicle systems that alert drivers to potential hazards received the highest safety ratings, whereas systems that facilitate vehicle control received the lowest ratings, and younger older drivers (55-64) demonstrated higher trust in safety systems than older drivers (65-75).
