The post introduces a Python library dedicated to quick local routing in the U.S., emphasizing its lightweight nature compared to more complex routing solutions like Graphhopper and OSRM. User comments scrutinize the library's usage of Dijkstra's algorithm for routing, noting its slower performance relative to other algorithms such as bi-directional Dijkstra or A*. There are also reservations about the term 'approximation' in the library's description, suggesting it may stem from assumptions about traffic flow based on incomplete datasets. Users appreciate the focus on non-AI technology, highlighting the library's potential while calling attention to necessary improvements in performance and functionality. An issue was noted by a user regarding challenges in accessing a large SQLite database associated with the library, likely due to proprietary software limitations.
