onehitwonder (1118559) writes WSJ looks at the cantankerous rivalry between two popular ride-sharing companies, Uber and Lyft, and the dirty tactics each employs to weaken its opponent. Lyft, for example, alleges that representatives from Uber frequently order short rides from Lyft just to slow down Lyft's service and to try to poach its drivers. WSJ points out that the rivalry is more than just a made-for-TV competition: "It's a battle for a key role in the future of urban transportation." Lyft certainly isn't Uber's only rival, though, even setting aside conventional taxis and car services, even those two names are big in U.S. cities: its clash with Gett has reportedly involved tricks at least as dirty. Another way to look at the rivalry, too, is that the biggest clash is not between Uber and any other particular company, but rather between the various ride-calling / ride-sharing services taken together against the existing, regulated taxi and car-service companies they threaten.
