1. Like most traffic laws, the DUI regulations are there to make it look like the politicians are doing something for "the good of the people" and generate revenue.
2. Idiots who can't/won't drive will be allowed on the streets as long as they continue to spend money on vehicles and oil, and it would require government to buy an effective public transportation system to take them off the road.
3. Drive through ATM's have the same buttons as the walkup kind because it is much cheaper to make them all the same.
4. Too impared is when there is a good possibility that you will crash and the cops will have to spend a lot of time filling out reports instead of hanging out at the donut shop.
