> I'm not sure why you think 20% of costs are fixed and 80% are variable This was based off the "Core Platform Financial and Operating Model" chart in their S-1, which states 75% of gross revenue is attributable to driver compensation. So, I imagine 80% is the low end. > I'm not sure why you think the elasticity figures are what you suggest they are I'm not sure on the elasticity figures. It's a guess based on running many pricing tests for my own business in the consumer services space. > If Uber raised prices by 10% and Lyft didn't, wouldn't bookings decrease further? This could be solved by acquiring them for $20B (or less, now). > Realistically, Uber has a higher cost basis than a taxi because taxis cut down on insurance and fleet expenses through pooling. I don't have too much insight into the taxi business, but in San Francisco, Uber Pool is substantially cheaper (<50%) than taxi fares. Again, I'm not saying my numbers are right -- only that it's plausible they can be profitable without SDC's.
