Uber's wayfinding logic in Manhattan is actively dumb. With billions of dollars they could just hire a thousand locals to sit in a passenger seat to give navigation instructions.
If a car is ahead of me on an avenue, even by half a street, it will send them around the block instead of suggesting I walk forward a bit.
Or, instead of asking me to cross an avenue, it will send the driver down a different avenue for multiple streets to loop back to my position.
It is obsessed with getting on to the expressways. It will happily crawl past relatively free-flowing avenues to squeeze into an expressway full of cars heading to Westchester.
Its estimates of ETA seem to assume that there is no traffic. They are hilariously bad.
Drivers, who have been burnt by customers getting mad at them for not going to an exact location or for "ripping them off", follow the map religiously. No matter what I text or call. They follow an app which was presumably written by people who've never set foot in this city.
