The in-car tech used by the likes of Ford and GM to make sure drivers pay attention to the road has come a long way. NHTSA says it evaluated 331 driver monitoring systems and found none that are commercially available that can properly handle identifying alcohol impairment. Driver monitoring isn’t the only option NHTSA has at its disposal, though. Accuracy is key, and according to NHTSA’s findings, blood alcohol detection tech is a more viable near-term answer. But this tech is considered “active,” meaning the driver has to proactively engage with the tech — which flies in the face of the law’s passive requirement.
