I'm curious, do you have a source for the claim that uber is profitable in most of the USA? That goes against their disclosed info of huge annual losses.
Where? I don't see any mention of profitability in CA in your link or in their actual report [1]. You might be referring to the "Results by Offering and Segment" where they report growth in the US and $1.8B in revenue, but they go pretty far to hide where their losses are actually coming from in relation to rideshare. It's not at all clear to me that they are profitable in any rideshare market.
