Which reinforces a point that I couldn't make above (because I had to go to a meeting) I also wonder if Uber/Lyft pricing below cost had to do with competing with each other? IE, if all they could do was compete on price, would that (cough) force them to undercut each other? If one decided to price below cost, would the other fear that they would loose too much market share too quickly if they kept their prices sustainable? Disclaimer: I am not an economics expert!
