// Restore sign
Why it didn't workWell, it did kinda work, but the problem is, OSM data is quite messy, and traversing graphs in real-time to find exits can lead to dead-ends if you're not on the right node or "component". I'm sure this was solvable, but I often found there was yet another edge-case every time I thought it was fixed. Side note: a very hard lesson learned in developing an app with map data - DO NOT USE HEURISTICS - YOU MUST FIX THE DATA.
