to solve this problem, volvo recently released a safety feature for its new generation electric suv ex90 - the driver attention reminder system. the system detects the driver's line of sight and attention level. once the driver stares at the road for a long time, the time is less than 60%, or more than 90%, an alarm will be issued to remind the driver to concentrate.

“we’ve done a lot of research within volvo and if you have 80 percent of your attention on the road, that’s normal,” said elsa eugensson, senior manager of volvo’s advanced driver assistance systems (adas) team. “if it’s below 60 percent, then you’re probably distracted and you’re not spending enough time looking at the road. but if you’re above 90 percent, then you’re probably ‘mind wandering,’ which could indicate you’re cognitively distracted and maybe you’re thinking about other things, things going on in your life.”

the new feature is the first attempt to address a problem we didn’t realize was happening before: even if your eyes are on the road, your brain may not be. this phenomenon is particularly prevalent in the age of modern devices such as smartphones and social media. what drivers need is a more powerful safety reminder to help them better control their attention.

volvo's new feature is not an isolated case. in recent years, many automakers have also begun to pay attention to the issue of driver attention. for example, tesla has launched an "autopilot mode" feature that can detect whether the driver is tired or inattentive and take appropriate measures, such as warning the driver or automatically braking.

in the future, with the development of science and technology and people's increasing attention to safety, preventive measures for driver distraction will be more perfect, thus providing more protection for drivers' safe driving and traffic accident prevention.
