BVZ's linked article makes it clear (see excerpt below) that the 'Alcohol Ignition-Interlock' is only activated for those CONVICTED OF DRIVING WHILE INTOXICATED...and by requiring all new cars to have such devices, that life-saving device can be activated immediately upon such a conviction...note that according to the National Highway Traffic Safety Administration, in a given year 1.5 MILLION drivers are arrested for Driving under the Influence of alcohol or drugs...
Of course, if you don't care about your life, your family members lives, or anyone else's life out on the road, then raise your voice in opposition to an effective remedy for DUI related fatalities. This is just like the seatbelt and airbag arguments, yet the results speak for themselves, and no responsible parent would want their kids driving without those devices now.

The issues of impaired driving and excessive speeding are both on the NTSB’s Most Wanted List of Transportation Safety Improvements. To prevent alcohol and other drug-impaired driving crashes, the NTSB has called for in-vehicle alcohol detection technology, the lowering of the blood alcohol concentration limit to .05 g/dL or lower, alcohol ignition-interlock devices for people convicted of driving while intoxicated and recommended that regulators develop a standard of practice to improve drug toxicology testing. The NTSB has also called for a comprehensive strategy to eliminate speeding-related crashes that combines traditional measures like enforcement and regulation with new technological advances like speed limiters and intelligent speed adaptation technology.
