Sites like Hacker News or https://i.reddit.com are still perfectly usable. In contrast to the 'modern' Reddit UI that that takes a couple of seconds to load even on my home WiFi.
Bonus points if it also lists the before and after streets at direction changes so people know if they missed a turn.
This could be implemented as a proxy to either of the maps apps (Google, Apple, OpenStreetMap)
On my phone it takes about 4-5 seconds to load even on Gbit WiFi. It's so bad I have a conspiracy theory that the pulsing Reddit orb is just on a timer and it's not actually loading anything. More likely it's just horrifically unoptimized I suppose.
