Officials say interlocks for first offenders are not a panacea but will reduce repeat offenses. They say the next step will be a program to develop devices to unobtrusively test every driver for alcohol and disable the vehicle. The automaker Saab and a medical equipment company already have devices that may be adapted for that job.
I doubt very much whether the American public is going to accept the idea of such sensors –“unobtrusive” or not. The installation of such devices in the vehicles of DUI offenders makes sense, but the idea that all vehicles would have similar equipment does not.
