They both use the same excuse. Public safety.
If you are not doing something wrong why worry?
Wrong on the first count. A detour, even a temporary one is not detainment without probable cause. Pulled over is police detainment and according to the constitution requires probable cause. The nourishment of tyranny on the second count. You are a dictators dream. Ever hear of this litle glitch in your sheep mentality? It's called presumed innocense. Learn it...know it...love it.
Government does not need your cheerleading. Greedy and power intoxicated people will always try to take more and control more for the taking.
Actually, driving is not a "right." It is a privilege. It requires that a license be issued by the State.
In order to protect the people on the roads (and close enough to it to be affected by motorists), the State has a very well defined and long recognized interest in issuing such licenses with conditions. One is that people amy not drive without a license. Another is that one may not obtain a license without passing certain tests. Another is that one may not drive at all under certain conditions (such as when one is intoxicated). And if a motorist violates these provisions, in order to fulfill its obligations to other people on (or near) the road, the State has valid legal authority to cancel licenses and to meet out punishment.
DWI is an area of overlap in that regard. Driving while drunk can get your license punched and get you criminally sanctioned.
To enforce the DWI laws, the State does have the legal authority to conduct traffic stops in a manner that is not otherwise inconsistent with our notions of fairness and justice. It's just one of the impositions one has ALREADY ACCEPTED as a condition of getting and keeping a driver's license. This is why roadblocks are considered Constitutional. Nothing about them allows for the officers to be arbitrary. ALL motorists get pulled over. No race consciousness. No sexism. No profiling. Equal application to all.
Can you make an argument that being "forced" to accept the conditions is somehow a violation of your liberty interests? Yeah. You can s
ay it. But don't count on your argument being found persuasive.
