Uber’s operations are orders of magnitude less complex than the supply chain and logistics of any major manufacturer. Or government or military. Or the post office or the phone company. Even McDonalds keeping its restaurants supplied and ice-cream machines working. All the cool tech Uber developed they did for fun. Because they had nothing better to do.
Hope this helps you understand.
This compares to Uber at 90 million passengers and 3.9m drivers: https://expandedramblings.com/index.php/uber-statistics/
Now unfortunately it's hard to assess Free Now's methodology as they're not a public company (they're owned by BMW and Daimler) so we only have their marketing claims to go on.
Also the majorly divergent passenger:driver ratio is likely down to mytaxi operating primarily in markets where taxi drivers are licensed and Uber's disruption not tolerated. This means they're pulling from a smaller pool that is more likely comprised of full time drivers.
They were called mytaxi until a couple of months ago, and absorbed Hailo and many other ride hailing services over the past few years.
No it doesn’t. For a start there is no overlap between cities, so that’s easy to shard. And secondly that’s not what SLA means - how many 9’s do you think would be in a sub-second SLA? Thirdly Uber offloads it’s payment to third parties, unless I blinked and it’s issuing its own credit cards now.
You seem to be incredibly impressed by Uber’s tech but have you considered that everyone else’s tech works so well that you just take it for granted? No Uber ride comes close to the complexity of sending a package internationally, and orders of magnitude more packages are sent every day than Uber does rides.
That's actually "for thousands of users in one city" executed a few hundred times, and map/PoI/pathfinding parts can be (are?[0]) outsourced to a third party.

[0] - I don't use Uber as a matter of principle, but the competitor I use utilizes Google Maps for these parts. So do food delivery companies I use.
