Just using the google answer for "how big is LA" doesn't really cut it as there are millions of people that live outside of LA proper but still in the region that most people would call "LA". If you go to Wikipedia for Greater Los Angeles it's 34,000 square miles. https://en.wikipedia.org/wiki/Greater_Los_Angeles_Area https://en.wikipedia.org/wiki/Greater_Los_Angeles_Area sqrt(34000) is nearly 200 miles on a side. And that doesn't really even cover all the areas that one might Uber from or to. So you'll have a lot of people crossing shard boundaries. Greater LA has some 18mm residents, and again that doesn't count some of the places very close but not really IN the area. Places you might drive to in 15 minutes from the edge, over a pass.
