Felix Salmon on iPhone controlled Uber cabs:

Uber loves to explain its surge pricing with fancy supply-and-demand curves, but you could call it a “rip off drunk people” strategy too. Mulligan has ideas about how Uber’s software could be improved: at the very least, it should display the current minimum fare prominently, rather than just the current multiplier.

I’ve never used the service, but as Salmon points out they start at roughly twice the price as a normal cab.
