I'm not looking forward to what these companies charge when (or if) they're ever profitable. I already find them expensive, especially Lyft.

the number will be higher in 2017 as they are expanding internationally (http://www.cnbc.com/2017/01/13/lyft-to-go-global-take-on-ube...), they are primarily still US only while Uber is in most of the world
Expensive compared to what exactly?
I'm not sure what other costs they can cut easily.
Unfortunately for them, second and third players entering the market has a huge advantage in terms of less spent on development and exploration, because they had an example to follow. Uber made the way for them, by building the app first, and testing regulators and authorities.
And there is nothing keeping Uber's user base from using competitors instead. They should probably have thought about some kind of reward system. Or anything to make their users invest and want to stay more.
I think they've got big problems. Problems that will be overcome better by their competitors.
Until Uber has self-driving cars, there's nothing to prevent local competitors from running a few subway ads and getting enough iOS installs to keep prices down. And unlike national competitors, which require hundreds of millions of dollars, local competitors can be run on the cheap. So even if Lyft goes bankrupt, I doubt that will have much impact on prices.
Driverless cars would throw a big wench into this however.
The only chance for Uber to survive is to be the first one in that space. I don't see how that can happen with so many companies in advanced development stages.
