This is what gets lost in all the negativity. Lyft/Uber can slash their R&D by 90% and they wouldn't have much trouble running normal operations as minimal app-based cab companies. At 2,000 minimally required head count for running operations, they would probably average $2B in annual expenses. However suddenly they would be gloriously profitable with huge scalable upside and small fixed costs. Here are some calculations: Currently per mile cost of car (fuel, vehicle, insurance) to driver is about $0.50. Uber/Lyft typically charge $2.00 per mile so $1.50 goes to driver. Subtracting cost of car, driver pockets about $1 per mile which translates to $30/hr in urban areas. One issue however is upper limit on the business. There is probably demand for 100,000 cabs each hour in US. That translates to may be 2-3 million miles per hour. if Uber can capture 30% of this, then their US revenue would be at about $4B. The international revenue perhaps adds another 2X so we are looking at total revenue of about $12B @ 30% market share. There is room to grow by almost 100% here in terms of market share so with $24B revenue and $2B of minimally needed fixed cost for operations, this seems fairly sustainable and astoundingly profitable business to me.
