I've never taken an uber from a place with hailable cabs. I would never have left a night haunt in Tottenham or a friends house in Denmark Hill and expect to find a taxi. Like, ever.

Sure, some cabs would be finishing jobs taking people home from Shoreditch and soho, but you'd just have to walk to a main road and hope you bumped in to one. Along with anyone else doing the same thing...
