Just found this forum and I’ve got to tell you one a local DJ did a few years back.
“Newsflash: New traffic lights on Park Square Roundabout (biggest one in town). They’ve got black boxes on the top that respond to loud noises. So when they turn red, honk at them and they’ll change.” This caused months of hassle and noise before a sign was erected to let people know that honking didn’t work. Makes me wonder why I’m still living in a City full of idiots!
