DUI laws were enormously controversial when they were introduced. So were seatbelt laws introduced around the same time. Many older drivers considered it an affront and refused to comply. Small town cops would let them go with warnings rather than take their licenses, until there was a horrific accident that made the news. States eventually took away cops' discretion, to again more controversy. It's only now, 3-4 decades on that it finally seems uncontroversial.
