It's undeniably more efficient to maintain a motor pool with a centralized mechanic shop. I get that the taxi experience was not ideal for you, but Uber did introduce a lot of inefficiency into the livery market by decentralizing maintenance, procurement, and financing. Uber was able to do this while undercutting incumbents on price through a combination of fare subsidies, consuming external capital resources (i.e., asking industry outsiders with "excess capacity" (cars that weren't on the road 24/7) to wear down their own private vehicles), and having investors willing to tolerating large, upfront losses.
