In many US cities before Uber, there was simply no way to get a cab when you wanted it. Markets match supply with demand but not when they're highly regulated.
I recall a few 45 minute hikes through San Francisco on a Friday night, futilely waving at each full cab that drove by
Most Uber drivers and customers I meet are very happy with the experience. Scores of them left traditional jobs to drive for Uber because they liked the pay and flexibility.
Some of regulation of ride-sharing seems to be done out of a spirit of bitterness that they aren't "following the rules", and it doesn't seem to be in benefit of anyone.
