Given what the drivers and passengers put into it, it does seem that Lyft's 20% cut seems high - but that 20% is also what justifies backing from the investors.

If so, then there's room for a service doing the same brokerage deal for, maybe 10% or 5% (if they cut out the lattes), advertising itself as "cheaper than cabs, AND cheaper than Lyft". Maybe Craig will offer a really crappy UI and do it for free?
