Vehicle=agricultural impliziert eine Straße für zweispurige Fzge. Also, ungleich path.
Vz240 kann durchaus auch auf normalen Straßen angewandt werden, mit den designated Tags.
Wiki sagt:
A highway=path is not for use by four-wheeled (two-track) vehicles. Often the path is simply too narrow. Other times it is wide enough but such vehicles are prohibited (except for official maintenance or emergency use). A path-like way where four-wheeled vehicles are allowed, is likely better tagged as a highway=track or highway=service."
