Not entirely the same thing but navigation and path finding for delivery apps is not a solved problem everywhere.
Especially in places where street data isn't complete or works differently (no street names) than in the western cities where Google Maps etc. are developed.
Grab (https://engineering.grab.com) always has interesting blog posts about these topics like: https://engineering.grab.com/road-localisation-grabmaps

The Grab engineering blog is pretty high quality, here's a related article from a few years ago that I liked: https://engineering.grab.com/correcting-restaurant-locations-harnessin…

Through my work I got to know this crowdsourcing solution to improve OpenStreetMap street views: https://en.m.wikipedia.org/wiki/KartaView
Operated now by Grab: https://engineering.grab.com/kartacam-powers-grabmaps
Disclaimer: I work for Grab (but not in the mapping team)

Elasticsearch apart from being an overkill for logging, I feel has a high cost of maintenance as the system starts to scale. Somehow that cost is not very visible in the start. One of the Singapore based successful start-up (Grab) had blogged about some other pain-points a couple of years back ( https://engineering.grab.com/how-built-logging-stack ) as well.
