The market they're going at seemed initially insane - how do you get your head around all the chaos that is ride sharing? But this is clearly a team that loved the idea and can execute beautifully. The hard out-of-the-comfort-zone work that I've personally seen Jason Shen put is probably worth a series of posts alone. On top of that, they're actually making the world better.

I don't know if they've announced their team motto, but I'd invite them to lay it out for inspiration on how to respond when someone asks why you're able to solve a hugely difficult problem.
