> In the case of taxi dispatch, a car may never show up, and you won't know until you get tired of waiting, and there are no consequences for the taxi company or driver if they do this.
depends on the country and the taxi company. England has a reasonably effective regulatory regime for taxis and cabs.
Sure, but both the article and my comment are both about the US, where there are no consequences for no-shows. I'm not sure our government(s) here are the best places to regulate that sort of thing. Uber/Lyft-style accountability seems to be working really well, though, and the mode of operation eliminates the possibility that a driver will cancel on you and you won't know about it.
