Well they actually operate at a loss, so it wouldn't be so surprising if you save money using uber instead of owning a car. Magic VC money subsidize your trips ;)
uber makes money on every ride. they operate at a loss annually because they invest everything in expanding to avoid paying taxes - like most companies do.
It's quite true that they make money on every ride - what I meant is that we get "cheap" rides while they try to win a "winner-takes-all" monopoly, because they can afford to "invest" in expanding, with heavy losses (4.5B in 2017).
It's also true that it's not sure they will ever reach profitability. Therefore, my comment.
