I've been hearing a lot about a program called DADSS - what is it?

DADSS is an acronym for Driver Alcohol Detection System for Safety.  It is a joint effort of the Automotive Coalition for Traffic Safetly and the National Highway Traffic Safety Administration to research many aspects of in-vehicle technology to prevent drunk driving.  

Currently, some drivers convicted of DUI are required to use an ignition interlock device, but DADSS is examining a more widespread technology that would be a part of every car, including those of drivers who never have been charged with DUI.
