This was a walking route. Straight line was with a nice wide sidewalk. Not sure why brouter was offering such a diversion!
In the brouter data probably missing the sidewalk along the main road. If you enter walking in the navigation, the navigation will try to find a road/way with less trafic.
You can check in OSM what features the site has on sidewalk. If properties are missing or flaky, that's the reason for this behavior. You can then correct these properties in OSM. A week later they are also at BRouter. Then all you have to do is update your BRouter files. Your BRouter files should be updated regularly.
Ah, excellent. I'll check it out and report it. Thanks for the replies.
