Uber vs taxi wait times: non-anecdotal evidence

More on the taxis vs. Uber in San Francisco beat.

I repeat my previous assertion that, anecdotally, ">20 min" is an understatement on weekend nights, and that the decision to use only 3 buckets ("<10 min", "10-20 min", ">20 min") conceals the long tail. As in so many other applications, tail latency has a disproportionate negative effect on on user experience, and looking at even the median or mean latency is insufficient: you should measure out to 95th percentile latency at least (n.b. this is standard procedure at Google).
