10 billion is a mind-numbing number. This announcement by Uber also shows how Lyft is still a baby compared to Uber. Lyft's at 0.5B vs. Uber's 10.0B.
"Last month, Uber hit 10 billion completed trips across rides and deliveries, the company announced today. This comes about one year after Uber hit five billion trips. Lyft, Uber’s main competitor in the U.S., hit half a billion rides last October."
