We’ve living in an exciting time for vehicle safety. Technologies that help drivers better perform their task – like the ones we see being offered as consumer options today – are helping to warn of driver drowsiness or an approaching vehicle, but none are able to accurately and precisely measure blood alcohol concentration (BAC). The Alcohol Detection System is a much more sophisticated piece of vehicle safety – taking a biomedical reading of someone’s BAC level to prevent a car from moving. To date, no technology has ever been developed that can passively and unobtrusively measure BAC with the necessary high levels of precision and accuracy while fitting into vehicles with a seamless operation. Additional research is required to meet the high standards we have set for measurement speed, accuracy, precision and reliability. While we have made great strides in the program, there is more work to be done before it can be introduced as a consumer option like the driver-assist technologies we are seeing today.
