China:
Shanghai - People's Uber (a Buick sedan) - Maglev station to Fudan University's main campus. 55 minute ride at 6pm rush hour: a slow, but never standstill, trek. RMB 48. Driver had glitches with the Uber app on his phone; we had to cancel and restart mid-trip.
Beijing - People's Uber (a Toyota Corolla, I think) - JW Marriott hotel to PEK airport. Driver texted me for my exact location; he said he tried to call but could not reach me. (I had an American cell phone.) Driver refused to go to PEK, and I was charged a cancellation fee (which was waived after I emailed Uber to explain the situation).
Beijing - Uber Black (Audi A6) - JW Marriott hotel to PEK. Driver agreed to go to the airport without hesitation. 41 minute ride at 12:15pm; some early snags in traffic gave way to a breeze to Terminal 3. RMB 151; compare to the RMB 80 taxi fare in reverse (which was in considerably heavier traffic).
