Uber is likely to survive in some form without one, they have the ridership and can use someone else's self driving cars in the future. They will just get a much smaller piece of the pie.
Uber's dominance in the taxi app space + Waymo cred?
But there are probably ways out of this for them. They will probably chug along for at least a decade and in that time anything can happen.
I personally don't feel there is that much price sensitivity in the market to make a 15% price increase cause volumes to dip substantially. I could of course be wrong, but it seems to me Uber is at a point they could be "instantly" profitable if they simply decided to be and decided to stop expanding.
- raise prices of uberX, price sensitive riders can still use POOL or Express POOL - reduce marketing and growth expenses; reframe KPIs and targets in term of "dollar ROI" instead of new rider/driver targets
Uber absolutely works from a unit economics perspective. How do you think taxis exist?
There are other costs that go into taxis that Ubers don't have. Taxis have back-office support staff too (the people you call up to order one to you).
Uber's a company whose current main product is software, that doesn't mean they can't branch out into new things and are forever tied to software. I'd also argue that Uber already has a lot more experience with working with a million different people than most other companies (currently drivers, in the future possibly mechanics, garage owners, etc).
