2. They are trying to monopolize the market. if you can put all other players out of business you can set whatever price you want. The government doesn't seem too interested in upholding anti-trust laws and uber knows this. also, I think the effect of taxis is also moot at this point. they are so expensive and inconvenient relative to their rideshare alternatives that few people I know use them.
3. They would eventually like to have self-driving cars as the default, and will almost certainly be profitable once that happens. It seems like they have struggled with this recently though and are pushing back the "launch date" further and further.
I would eventually like to win the lotttery and will almost certainly not have to worry about money once that happens.
I don’t know if I’m the crazy one here, but I just can’t see this self-driving car end game coming inside of 10-20 years. And can Uber really drag their feet and remain solvent that long? And is it even certain that they’ll be the “winner” in a self-driving car world?
Math doesn't support Uber's or Lyft's case, but you never know.
Since it's a winner-take-all market - because of the network effects on both sides of the platform - they need to acquire users faster than any other competitor.
They'll stop when they know they're the clear winners of the market.
