I don't know what Uber did to make their implementation of GPS so terrible. Google maps can definitely have issues at times in Chicago but I rarely see an Uber driver use the built-in mapping. They use Google maps.
Side note on Uber express, if it says northeast corner, it will always be the southwest corner.
Lyft doesn't even have their own maps. Drivers get to pick between Waze or Google Maps [1].
Google Maps is so much better than anything else.

It doesn't work with Google Maps. Source: I was using Google maps to get to/from Northwestern Hospital on Lower Wagner today, and the GPS dropped the entire time I was down there.
Trick: as you enter Lower Wacker, take note of the proposed exit.
And then head in there. Ignore your GPS. Make a turn when you see your exit.
When you're above ground again, resume GPS.
Yeah, did that. Problem wasn't the initial exit, it was the rapid series of turns after exiting lower Michigan from lower Wacker that was the Problem. Took a few loops around the block before the GPS reacquired. I used to spend a bit of time in the area, but it was always on foot. First time really driving in that area (coming in from West suburbs, normally, I'd take Metra and walk/cab it), and first time to NW hospital (wife needed to see a specialist)
Yeah that can be a pain. The GPS will tend to swing around for a couple seconds before getting a lock again.
My Google Maps still goes a little crazy on Lower Wacker.
Also we need beacons in the loop. All those tall buildings really mess up navigation downtown.
