This is an honest question...what would you consider to be constitutionally valid, and also effective, method(s) that police may take to remove DUI/DWI drivers from public roads?
That's easy... PROBABLE CAUSE.
In United States criminal law, probable cause is the standard by which an officer or agent of the law has the grounds to obtain a warrant for, or as an exception to the warrant requirements for, making an arrest or conducting a personal or property search, etc. when criminal charges are being considered. It is also used to refer to the standard to which a grand jury believes that a crime has been committed. This term comes from the Fourth Amendment of the United States Constitution:
All the kings horses asses have done NOTHING to get DUI off the road. If they crash, throw the book at them. If they don't, no problem. Innocent till crime is committed is how it works.
There is no effective method in place as it is now. According to MADD’s website, 300,000 people drive drunk every day; 4,000 are arrested each day, resulting in 1.2 million arrests each year and 30 die each day. According to the CDC, the “annual cost” (whatever that includes) is $59Bil. That’s not control of a problem.
Computers in cars can already recognize erratic driving and On-Star (Lojack?) can shut vehicles down - so let’s take technology one step further and free the cops up to do other types of crimefighting at the same time.
I’d suggest the most effective method of control would be to toss the issue back to the auto manufacturers/salesyards and make breathalizers in autos (and planes and trains and motorcycles) as commonplace as air conditioning and power brakes. (key-fob based even?) With mandatory retrofits on saleslots on older models via government voucher. No blow, no start. Drive erratically, computer starves the gas to a slow stall. Calibrate annually at smog check. Could use of in-vehicle techology be more cost effective and focused than the easter-egg hunting policies in place now, and help protect constitutional rights while reinforcing driving isn’t?

What “common sense” measure would you support to remove drugs from our society?
Feel free to compare and contrast “random automobile stops” for DUI and “random house searches” comlete with canine search for illegal drugs.
