Compared to SF, oh yes, much better! The most common taxi in Stockholm is probably a Mercedes, and the average car of the kind of people who would want to drive for Uber is definitely not. I don't see how Uber could mobilize a comparable fleet to compete with that. I can see UberPool working where people expect a "regular" car, and I could see them becoming the dispatch of choice for non-affiliated taxi drivers, but that's the bottom of the barrel of that market.

If people think that taxi markets everywhere look like the one in SF, then I understand why people value Uber so highly and think they'll conquer every market easily. But the truth is that Uber doesn't have anything that isn't easily replicatable by entrenched taxi companies that are willing.
