If DUIs are a problem, they should implement No-Refusal Weekends, like Texas and other states do: https://www.nhtsa.gov/staticfiles/planners/NoRefusalWeekend/index.htm

All holidays where drinking is big (Fourth of July, Halloween, NYE, etc) should be no-refusal weekends.

But then again, in other states, cops don't unnecessarily harass citizens trying to catch them with the force of institutional power like MA, because they have nothing better to do except steal pension money
