How Cars Know if You’re Sleepy or Distracted

Oxygen, heart-rate and other vital signs

It’s clear that distracted driving is a serious concern when it comes to road safety. But so far, the automakers have been focusing to factors outside of the car, using cameras and radar to assess a risky situation. The next step is to monitor the driver in the car. Ford and Toyota have already been testing the idea of biometric sensors that can tell whether you’re stressed, at risk of a heart attack or even have low blood sugar, ensuring you’re in good physical condition to drive safely.

Hyundai is even using some of this bio-science in the brand new 2015 Hyundai Genesis, relying on chemistry to combat drowsy driving, instead of data and statistics. With a built in Carbon Dioxide (CO2) sensor,  the Genesis can detect if there is a higher than normal build up of CO2 found within the cabin. Too much CO2 and you can feel sleepy, so the car will open up the vents to allow fresh air into the cabin, helping to battle drowsy driving. 

Automakers have several high-tech safety nets in place for when you’re feeling drowsy or not paying attention, but the onus still falls to the driver to ensure any internal distractions, like cell phones are put away and out of reach while driving.
