Modern cars have standard features like power windows, locks, A/C, video screens and yet no breathalyzer lock-outs? Something so basic that would save so many lives and tax-dollars in such situations would seem to be a bargain. Making a fourth DUI a felony is a good start, but by then it may have cost hundreds of thousand$, many  lives & much innocent suffering trying to get alcoholics to stop driving. Surely a simple breathalyzer ignition lockout would be cheaper? At least make it mandatory after the first infraction.
