Well (at the risk of stating the bleeding obvious) we can actually see
data that says "maxspeed=0" rather than just wondering why we never
actually get routed from A to C via B.
I guess it varies from place to place, but well-mapped areas tend to be
effectively "gardened" so that odd or out of place edits get spotted at
some point. It might not be immediately, but I bet it'd get spotted.
People use various methods (e.g. OWL) - I use a combination of ITO's
tools and something that checks for stuff I've previously edited
whenever I create a new Garmin map.
Cheers,
Andy
