'While the provision doesn’t dictate what type of tech has to be in these vehicles, industry experts believe that companies developing camera-based driver monitoring systems (DMS) stand to benefit the most. DMS systems are already mature in the auto industry, representing a technological byproduct of autonomous driving developments. While the auto industry explores self-driving cars as a way to drastically reduce road deaths in the future, advocates and regulators say there's room to use some of this tech to solve problems that exist now, like drunk or distracted driving.
“What's happening in the U.S. Senate this week potentially opens the door to a camera-based real-time solution, which will be the first time that the U.S. automakers will have the ability and the requirement to look at real-time physiological changes in your body that occur when you are inebriated,” Dr. Mike Lenné, chief science and innovation officer at Seeing Machines told TechCrunch. "There are distinct reliable changes to the way you scan the environment, to the way your eyes respond to stimuli, which is why the police use that ‘follow the finger’ test."
The system would have to monitor the performance of a driver to detect impairment and prevent or limit vehicle operation if impairment is detected; detect whether BAC (blood alcohol concentration) is equal to or greater than the legal limit, potentially preventing operation of the vehicle at all; or a combination of both systems.
Cameras aren't the only solution that has been trotted out in recent years.
The Driver Alcohol Detection System for Safety (DADSS) program, a technology that’s been developed in partnership between the Automotive Coalition for Traffic Safety and the National Highway Traffic Safety Administration (NHTSA), has advocated using a breath or touch-based approach to determine BAC levels. The touch-based approach involves measuring BAC through the skin's surface by shining an infrared light through the driver's fingertip. According to DADSS, the current timeline for bringing the breath-based approach to vehicles is by 2024, and the touch-based approach by 2025.
Lenné argues that a camera-based approach would be far more successful than a breath or touch-based approach because BAC levels can rise within minutes. Someone could theoretically down a bunch of shots immediately before getting behind the wheel and it wouldn’t show up on a reading for several minutes. Or they could get wasted while driving. And BAC detection doesn’t help at all when it comes to drug-impaired driving. '
