The technology is called Driver Alcohol Detection System for Safety, or DADSS for short, works in two ways: a breath based system or a touch-based system. Watch the video above for a more in-depth look at how the technology works.
The breath-based system detects and analyzes the driver’s breath within seconds of entering the vehicle and determines if their blood-alcohol level is within legal driving limits. The touch-based technology could be installed in the push button ignition and can detect ethanol (alcohol) levels in the driver’s finger.
Apparently, it works like this: if your car starts and it’s later determined that your blood-alcohol is too high for the legal limit, then it will completely disable the vehicle – obviously, an attention grabber for law enforcement.
The technology is slated for implementation in around 14 to 20 years.
My opinion? Completely disabling a vehicle could be more dangerous than necessary.
