I've seen a lot of misuse of access aisles (not you! just generally) but I think they're pretty clear (when they are, at least). As for algorithms, I might sometimes spot check something in BRouter.de but mostly, if something doesn't work in RidewithGPS, I'll make changes in OSM. Thanks for reaching out. I'm glad we had this discussion. Please feel free to tag how you think is best, as I don't live anywhere near Forks Twp anymore (and only visit a few times a year, if that). I trust your local knowledge and discretion!
