The user mentions their reliance on tools like Gravelmaps and Google Maps, particularly Street View, to assess road conditions. The planning process is described as labor-intensive due to the exploration of various route permutations, indicating a need for more efficient tools. The user suggests a potential improvement for Gravelmap to allow for route optimization between two points, as well as a feature in Google Maps that could filter for gravel routes. Alternative platforms like Strava and Komoot are also considered useful for their heat maps which reflect popular cycling paths, though the user finds them lacking in efficient planning capabilities.
