I've been on a visit to London and one thing that struck me was that the pedestrian crossings don't make any noise to let you know when to cross. I understand that it's for blind people but it's what everyone (including me) seems to use as a signal in my city. Every time that I've been at a crossing in London, I've been left standing at the crossing not looking for the green man as I was waiting for the noise! I've just thought that maybe it's only where I'm from where the lights 'peep'. AIBU to think this is odd?
