I would prefer that vehicles be able to detect if a person is drunk. If so, then touching the drivers seat, steering wheel, or shifter would result in a large electrical shock!
@Retired_Engineer: Problem would be that alcohol is not the only drug that will make someone DUI....sleeping pills, antidepressants, antianxieties, pain pills, hard narcotics, even pot can affect someone ability to safely drive. A breathalizer will not detect any thing like that. IMO texting and driving is as bad as drinking/drugging & driving, anyone driving distracted or impaired needs to let someone else drive.
