The share to the driver is so small I can’t believe they get away with it (Lyft too). In SF I often see drivers accepting their next fare while I’m in the backseat. A ride that will cost me $15 might get them $6. I know Uber’s part here is not trivial (it’s good software and they do support, etc) but surely the driver should be getting more like 80% or even 90% given that it’s their time, their equipment, etc. Most other marketplaces take smaller cuts.
