You cannot legislate morality when dealing with drugs and alcohol. A car simply should not start if a person is impaired. People will continue to die as long as people profit on those deaths. People want to blame the drunk, but the whole system from liquor peddlers, restaurants, the criminal justice system, and all the ancillary tapeworms live off the certainty that drunks will drive. Interlock ignition control would eliminate 95% of the 30k folks a year injured or killed by impaired drivers........but then what would the lawyers, jailers, judges, public defenders, police officers, prosecutors, probation staff, prison guards, and the liquor peddlers do if folks realized that if they drank too much their car would not start.....nope.....there is profit in death.....and each time someone dies......more outrage at the drunk.....more profits for the tapeworms......and more families grieving the loss of loved ones.....Insanity is doing the same thing over and over and expecting a different result.
