Here's a better headline: "My Uber gor pulled over by the Denver Police, and the officer mistakenly told us Uber is illegal." Maybe not so many clicks that way, though.
I agree that this was a rather unfortunate and odd experience, but I don't see what the big deal is. The only thing that struck me as "really weird" about this is that the author called a Denver Post reporter to get live legal information while he was in the car, and that the author wrote this sentence: "Did I really want to take a ride from an individual who clearly lied to me, then was evasive when I asked one basic question?" (Did it ever occur to the author that the cop might just have been mistaken about Uber's legality? Did it occur to him the the officer was just trying to do him a favor?)
At the end of the day, we have a cop who pulled an Uber driver over for speeding and, though he mistakenly thought Uber was illegal, nonetheless only issued a speeding ticket and offered to drive the passenger to the airport. The author goes out of his way to pain the officer as behaving "really weirdly," and I suppose I don't see why the officer needed the passenger's ID (though I also would not be surprised to learn that it is totally normal for an officer to request a passenger's ID), but for the most part this seems like everyone did their jobs properly.
Of course, in a perfect world, an officer would know everything about Colorado law. But that is clearly unrealistic. So while yes, of course, it would be preferable for an officer to be properly informed about Uber's legality, I don't think we should be judging him too harshly for his mistake, especially when it sounds like Colorado has only recently legalized Uber, and the officer did not attempt to ticket or detain anyone for the purported violation.
Edit: By the way, the Colorado law imposes a number of requirements. Companies must obtain permits, drivers must display various notices and "[t]o obtain permits, the companies must have drivers pass criminal-background and driving-history checks. The drivers' cars must pass vehicle inspections, and be clearly marked as ['transportation network company'] cars. The drivers must also carry personal car insurance, in addition to the commercial insurance Uber and Lyft provide." http://gazette.com/uber-lyft-become-regulated-in-colorado/ar... Nothing in the article on whether Uber, or his Uber driver, has complied. The officer could well have been correct (though perhaps not for the reason he was thinking).
