Beware – Driverless Cars Aren’t a Zone for Relaxation

    Unsafe Activities in Self-Driving Cars: Early Data Reveals Surprising Results

    Self-driving cars hold great promise for the future of transportation. With the potential to reduce accidents caused by human error and increase efficiency on the roads, autonomous vehicles have generated significant interest and investment. However, as the technology advances, it is becoming increasingly important to understand the limitations and potential risks associated with self-driving cars.

    A recent study conducted by RMIT University has shed light on activities that may be unsafe to undertake in automated vehicles. The researchers focused on scenarios where a driver needs to take control of an autonomous vehicle, particularly during emergencies. The study aimed to investigate the influence of experience and various forms of distractions on a driver’s ability to respond effectively in such situations.

    The study involved a simulation of Level 3 automated driving, where the human driver still needs to be prepared to assume control of the vehicle in case of an emergency. Participants were assigned tasks that required different levels of mental workload, including work-related activities, social media use, and relaxation. The researchers then assessed the participants’ speed and effectiveness in taking over the vehicle when faced with an emergency.

    The findings showed that distractions significantly impaired a driver’s emergency response in semi-automated vehicles. Resting resulted in the poorest takeover response, followed by work-related tasks. Surprisingly, social media use was found to be less disruptive but still had a negative impact on the driver’s response. Furthermore, the longer the participants engaged in an activity, the worse their response was to an emergency.

    It is crucial to consider these results when developing regulatory policies for the use of automated vehicles. Dr. Neng Zhang, the lead author of the study, emphasized the need for authorities to draft regulations that ensure drivers are given enough time to respond quickly and flawlessly to emergency events. The data gathered in this study serves as a starting point for developing data-backed legislation that prioritizes road safety in the era of autonomous driving.

    Currently, there are five levels of vehicle automation, with Levels 1 and 2 already common in features such as lane keeping and automated parking. More advanced automated vehicles, commonly known as “driverless cars,” are currently being trialed but are not yet commercially available in Australia. However, as Level 3 and 4 automated driving approaches, it becomes increasingly important to establish regulations and address potential risks associated with these vehicles.

    The study also highlighted the impact of experience on a driver’s ability to respond effectively during emergencies. Inexperienced drivers, particularly those with less than 20,000 kilometers of driving experience, exhibited slower and less effective response times. This suggests that the distance driven since gaining a driver’s license is a more significant factor than the number of years since obtaining the license.

    The cross-disciplinary nature of the study brought together expertise from RMIT University’s School of Engineering, School of Health and Biomedical Sciences, and School of Science. This collaboration enabled researchers to explore the influence of human body vibration, automotive engineering, and cognitive psychology on driver response capabilities.

    Professor Stephen Robinson, a biomedical researcher involved in the study, emphasized the importance of drivers’ full cognitive abilities in assessing unexpected situations and taking appropriate action. Emergencies require quick thinking and decisive actions, and it is essential to ensure that conditionally automated vehicles do not compromise the driver’s ability to respond effectively in such circumstances.

    As the research team continues its work, they are investigating ways to enhance driver alertness and improve the effectiveness of driver takeovers. The goal is to achieve a seamless and safe transition between vehicle automation and human control, leading to increased efficiency and safety on the roads.

    However, it is important to note that engineering and design alone cannot address all the challenges associated with autonomous vehicles. Regulations need to be put in place to address issues such as distraction, alertness, and driver experience. By acknowledging the detrimental effects of certain activities and regulating non-driving behaviors in the context of autonomous driving, governments can effectively safeguard road safety.

    The study conducted by RMIT University provides valuable insights into the potential risks and limitations of self-driving cars. The results emphasize the need for robust regulations and policies that prioritize the responsible use of autonomous vehicles. As Level 3 and 4 automation approaches, it is crucial to ensure that drivers are adequately prepared to assume control of the vehicle in emergencies. By addressing these considerations, we can pave the way for a safer and more efficient future of transportation.
