New Study Reveals Increased Driver Distraction with Partial Automation Systems

Insurance Institute for Highway Safety (IIHS) study shows increased driver distraction with partial automation systems. Tesla's Autopilot and Volvo's Pilot Assist were the focus of the research. Drivers were found to engage in non-driving activities more frequently when using these systems.

The research, conducted by the Insurance Institute for Highway Safety (IIHS), suggests that drivers are more prone to engaging in non-driving activities when these systems are active, potentially compromising road safety.


The month-long study focused on two popular partial automation systems: Tesla's Autopilot and Volvo's Pilot Assist. Researchers examined how driver behaviour evolved over time when using these technologies, which are designed to assist with routine driving tasks such as maintaining speed and staying centred in a lane.


IIHS President David Harkey emphasised the importance of the findings, stating, "These results are a good reminder of the way people learn. If you train them to think that paying attention means nudging the steering wheel every few seconds, then that's exactly what they'll do."


The study involving Tesla's Autopilot included 14 participants who collectively drove over 12,000 miles with the system engaged. During this time, the system triggered 3,858 attention-related warnings. On average, drivers responded within three seconds, typically by nudging the steering wheel, which usually prevented further escalation of the warning.


In the case of Volvo's Pilot Assist, 29 volunteers participated in the study. Researchers found that drivers were distracted for a staggering 30% of the time while using the system. The study's authors described this level of distraction as "exceedingly high".


These findings come at a time when major automakers are racing to develop and deploy partial automation technologies. While the goal is to make driving easier and safer, the study highlights potential risks associated with these systems. The rush to implement such technologies has already sparked concerns and litigation surrounding driver distraction and related accidents.


Harkey stressed the need for improved safeguards, saying, "In both these studies, drivers adapted their behaviour to engage in distracting activities. This demonstrates why partial automation systems need more robust safeguards to prevent misuse."


Partial automation systems, classified as a level of "advanced driver assistance systems", utilise cameras, sensors, and software to regulate vehicle speed based on surrounding traffic and maintain lane positioning. Some systems even offer automatic lane-changing capabilities.


Despite these advanced features, it's crucial to note that drivers are still required to continuously monitor the road and be prepared to take control at any moment. Most systems mandate that drivers keep their hands on the steering wheel as a safety measure.
