Cheap Drunk Driver Detection From UofM
University of Michigan researchers are proposing a low-cost system that could detect drunk, drowsy or distracted drivers before they get on the road—or while they are on the road.

“In many new vehicles, Advanced Driver Assistant System (ADAS) cameras are already onboard to track driver alertness. They’ve already been matured and are cost effective.”[Professor of Electrical & Computer Engineering Mohammed] Islam’s team proposes augmenting existing ADAS cameras with infrared Light Detection and Ranging (LiDAR) or structured light 3D cameras costing roughly $5-$10. Their proof of concept experiments, which interpret data captured by the 3D cameras with artificial intelligence tools, can identify five signs that a driver may be impaired.
The team demonstrated that the system can measure vital signs, detect drowsiness and provide data that correlates with breathalyzer readings. The researchers are now working with Tier 1 auto suppliers, including DENSO, and Tier 2 suppliers that make the cameras to further develop and potentially commercialize the technology.
The system is cheaper and harder to cheat than in-auto breathalyzers, which could cost as much as $200 per vehicle...

Science fiction great Philip K. Dick is way ahead of us in his 1963 novel The Game Players of Titan; he knew that cars would someday keep a sharp eye on us mere humans:
It had been a bad night, and when he tried to drive home he had a terrible argument with his car."Mr. Garden, you are in no condition to drive. Please use the auto-auto mech and recline in the rear seat."
Pete Garden sat at the steering tiller and said as distinctly has he could manage, "Look, I can drive... Start, darn it!"
The auto-auto said "You have not inserted the key."
"Okay," he said, feeling humiliated. Maybe the car was right...
