British roads are ever-more cluttered with nannyish and often pointless signage. My pet hates are those boards instructing 'pedestrians' to walk around the fenced-off 8ft deep hole some gas company or other has dug, rather than attempt to walk through it. Cheers. Thanks for that. In the US, hackers have been risking $250 fines by tampering with road signs in Texas and Illinois. Presumably these are a genuine warning in the remoter bits of Louisiana.
