I saw this in Yahoo News.
Motorists convicted of driving drunk will have to install breath-monitoring gadgets in their cars under new laws taking effect in six states this week.
The ignition interlocks prevent engines from starting until drivers blow into the alcohol detectors to prove they're sober.
Alaska, Colorado, Illinois, Nebraska and Washington state began Jan. 1 requiring the devices for all motorists convicted of first-time drunken driving. South Carolina began requiring them for repeat offenders.
Mothers Against Drunk Driving has been conducting a nationwide campaign to mandate ignition locks for anyone convicted of drunken driving, claiming doing so would save thousands of lives. But critics say interlocks could lead to measures that restrict alcohol policies too much.
Then I found this online.
I think these are the "critics" that they are talking about.
