Can you provide an example? What is different about running Uber services in Chicago vs. Indianapolis?

Vegas: ordering a tax "to a hotel" - hotels have different entrances, pickup / dropoff there during crazy times is hard. Uber UI for Vegas is unique / some features are designed to make it easier for driver and passanger to find each other

Airports: different regulations, different rules for pickup/dropoff. Also scammers who pretend to be in a car, walk with their phones around pick-up ares in airport and do bait-and-switch (saw that in Istanbul SAW and in Dubai Al Maktoum)

For example in Seattle you pay county fees, and then state fees, and then maybe special fees if you were picked up in the airport.

I took a ride from SEATAC to my hotel in downtown Seattle and besides the ride itself, there were 5 other items on the bill, 4 of which are specific to the place I used Uber.

Then I had the return trip from my hotel to SEATAC, on this one I got EIGHT items on the bill, on top of the ride fare. Some specific to Seattle itself, some specific to the road that the Uber took (a tunnel fee - which is different based on the direction you take it in), etc.

So the real question is what is NOT different between two locations. Less than 15% of the bill.

I also took Uber in India, where you have to share a one-time password with the driver for example, which I've never seen in any other country.

In some other countries the Uber app exists but Uber drivers are actually taxis, so you're actually ordering a taxi via the app.

		Uber has also been public transit: https://www.theguardian.com/cities/2019/jul/16/the-innisfil-... (like actually public transit, not "lol they reinvented busses again" (though, lol, yes that too)) Essentially every single airport in the world is custom UI and custom walking path guides and pickup instructions, and rules for where pickups/dropoffs/etc can occur can change multiple times in a day, much to everyone's enjoyment. They're almost all private property, and are so valuable that whatever they want is what they get. And food. Most/~all? major brands get custom integrations. Hundreds (iirc) of identity verification providers, most or all custom, and constantly weighed against cost and accuracy because it ain't cheap and it ain't good but it is far better than none (both legally and ethically). No idea how many payment sources they accept, but it's definitely a lot more than anyone who hasn't lived on 5+ continents thinks. And remember that this is all international. So scale is huge and law changes are constant and frequently conflicting. Darn near every useful feature is illegal somewhere, at some time, for both good and bad reasons. --- This is not at all to say I think Uber is efficient, clearly it is not. Not by an enormous margin. But there is a legitimate need for truly absurd complexity, because the world is not consistent. You see similar things happen anywhere [thing] tightly interacts with humans.

		Ah local regulations and fees. Not so much the core service algorithms. That makes sense.

There's an excellent HN thread that talks about this very question (that comes up on HN every now and then - what _does_ company X do that needs so many engineering resources?): https://news.ycombinator.com/item?id=25375921

TL;DR: Managing a taxi service (that's what Uber is in my mind, not whatever "ride share" means) that spans cities and states, never mind countries, is extremely complicated. To their credit, Uber manages to make it look simple to the end user, prompting such comments as "meh it's just a few screens how hard could it be", which is triumph of product engineering as far as I am concerned.
