Uber chief executive Travis Kalanick was typically outspoken at the WSJD Live event in California on Tuesday night.

He commented on a range of topics, such as China now accounting for 30 percent of its rides (soon to surpass the U.S.), Uber’s struggles against censorship on China’s popular mobile messaging app WeChat (now with 600 million users), Beijing catching up with Silicon Valley, Uber drivers and the future of driverless cars, why he won’t introduce tipping, launching in new cities, the question of an Uber IPO, and U.S. competitor Lyft (recently backed by Uber’s China rival).

There are lots of great titbits from the interview, and we’ve pulled together the best via Twitter for you here.
