Uber pool is becoming a real and separate disruptor that seems to compete more with public transport than taxis. I would like to see stats on what's happening with buses and subways. In Miami it's about the same price to take an Uber pool ($2.50-$3) as it is to take a bus ($2.25), while being significantly better. UberX feels like Netflix's DVD phase, a precursor to the real, defensible, network-effect dependent, technologically more challenging [1], core competency of pool.
