San Diego DUI lawyers believe there are many problems with a built-in ignition interlock device that prevents cars from starting if the results of their breath are .08% or higher.   Breath testing is not a perfect science.  There are numerous interferents, false positives and other issues which make this a bad idea, say San Diego DUI attorneys.

The Los Angeles Times today reports NHTSA and a coalition of 17 automakers are working on the so-called Driver Alcohol Detection System for Safety. The DADDS system uses sensors in the cabin to measure blood-alcohol content by breath or touch to ensure a driver is below the legal 0.08% threshold for impairment.
Safety advocates and anti-drunk-driving groups support technology that grounds motorists before they can hurt themselves or others.
But some have reservations about these high-tech minders. The restaurant lobby opposes what it sees as an encroaching nanny state. Some analysts predict the equipment could add hundreds of dollars to the cost of each vehicle. And even some car enthusiasts say that imperfect technology could alienate the public it’s supposed to protect.
Jack Nerad, an analyst with auto information company Kelley Blue Book, imagined a scenario in which sensors picked up alcohol on the breath of passengers, preventing the designated driver from getting them home.
“You are reliant on the technology to be 100% perfect or your car doesn’t start,” he said. “That makes people very, very angry.”
The public balked and a cottage industry sprang up to help drivers bypass the system, said Jeremy Anwyl, an automotive industry consultant and former chief executive of Edmunds.com. Then-President Gerald Ford beat a hasty retreat, ordering NHTSA to abandon the requirement for 1975 cars.
Anwyl suspects renewed efforts by government to keep tabs on driving behavior will elicit a similar outcry.
“People won’t like the idea that all of a sudden they are no longer completely in control,” he said. “They might not buy a new vehicle and instead just keep the car they have.”
But increased awareness of the dangers of alcohol and distracted driving has some consumers eager to see the changes.
There could be glitches. Mistaken alcohol readings or faulty seat-belt sensors could put motorists in harm’s way if they’re stranded during emergencies or in remote places.
Where the DADDS system will set the blood alcohol limit could also prove contentious.
NHTSA says it will be the .08% level at which a driver is legally considered impaired, a ceiling that is supported by Mothers Against Drunk Driving.
“There will be no ifs, ands or buts about that,” said J.T. Griffin, MADD‘s chief government affairs officer.
But a slightly higher limit might leave a margin of error that reduces false positives without greatly increasing the frequency of drunk-driving crashes, said Clarence Ditlow, executive director of the Center for Auto Safety.
The majority of people who were killed in drunk-driving crashes last year were in collisions in which a driver had double the legal limit, according to NHTSA data.
Some groups are already voicing objections, regardless of where the threshold is set.
“We are opposed to mandating this technology on all cars as original equipment,” said Sarah Longwell, managing director of the American Beverage Institute, a restaurant trade association. “You are not going to solve the drunk-driving problem, which is a small, hard-core population of offenders, by treating everybody like a criminal.”
She said drinkers could find ways to evade the technology. For example, they could quickly throw down some shots and already be on the road by the time their blood-alcohol level crosses the .08% limit.
“And then what is going to happen?” Longwell asked. “If you crash your car and you are well above the legal limit, can you sue the manufacturer? Who has the liability?”
Field testing of the DADDS system will take place at the NHTSA lab in Boston over the next two years. The government has not yet set a date for automakers to install this and other safety technologies in new vehicles, but NHTSA’s Strickland says he wants to get them into cars as soon as possible.
Automakers have been down this road before. In the early 1970s, more than 50,000 people a year were dying on U.S. roads. In response, NHTSA mandated a seat-belt monitoring system that launched in the 1974 model year. It prevented vehicles from starting unless the front seat belts were fastened.
