It is me, or does that article not talk about any of the actual uses of this valuable data they've collected? It is an interesting idea, might be useful here in Manchester (UK) where in the city centre (and possibly only one weekends) black cabs aren't allowed to pick people up from anywhere, only from the designated taxi ranks. This service means that you can still get a cab directly to you. Not sure why it's limited to black cabs though, surely ordinary taxis would be suited to this just as well.
