That type of ride from a "hub" where a bunch of taxis congregate to take the next passenger -- such as SEATAC airport -- is optimal for traditional taxis and can be cheaper. But using Uber for suburb-to-suburb routes away from any hubs is cheaper than taxis and I tried to explain why that happens: https://news.ycombinator.com/item?id=30660517
I can wholeheartedly understand complaints about Uber and Lyft, but I don't understand at all when I sometimes see this collective amnesia about how much taxis sucked before rideshare came on the scene.
Every Uber or Bolt can also operate as a taxi since the regulations stipulate that any private passenger transport service is the same as a taxi, and has to follow the same regulations.
