Don't worry about it. Near me there is a footpath, 20ft wide and all of 20ft long. The council have put up a huge notice "Cycling along this path is strictly prohibited". Just like they have also marked out cycle and pedestrian paths across a park. They have put PEDESTRIAN CROSSINGS across the cycle track (which is 4ft wide) in the middle of the park. A silly little zebra crossing in the middle of nowhere.
An axiom for you - if the law is silly, then break it.
