Think about landing at an airport in the before times and getting an Uber. You don't just put a marker on a map view, you have to be directed to where the airport set up ride share pickups. The drivers who want to wait in a queue to pickup airport riders need to be told where they're allowed to wait. There are millions of little edge cases like this, all with different, non-standard laws in every city they operate in. It's not just running a big server that keeps a table of pickup coordinates.
