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.
