As far as I am concerned you should be given 20 stripes with a cane on the first offense, 50 on the second and executed on the third DUI.
Punishment isn’t (or shouldn’t) be about punishing a law breaker. It should be about deterring behavior. Drunk drivers, through depraved indifference, kill, burn, and maim people. The punishment should be severe enough that the act becomes rare. Very few people will put themselves in a position to drive drunk after once having had their ass carved up by a split bamboo rod.
Why Western culture tolerates so much violent criminal behavior is beyond my comprehension. And why we build monster factories called prisons is also beyond my comprehension.
This isn’t Saudi Arabia.
The main purpose of DUI laws appears to be, in my view, to raise revenue for state and local governments. That is why they have lowered the limit to the point where most people are not impaired and have set up a regime of collections so that a DUI costs many thousands of dollars in fees and fines. In my state, you can get a conditional license and be driving again pretty soon. If it were really about deterring people the punishments would be more about jail time and less about fees and fines. I have never had a DUI but know many people who have and they were legally driving again soon after their arrest, for a hefty fee to the state of course. I don’t recall any of my acquaintances spending more than a night in jail for DUI.
