Here's something interesting about traffic lights in Australia . We used to have a version of the ones you refer to here .

Apparently these types of lights were phased out because people used to race them . What I do like is the orange flashing lights that warn of an imminent change that have recently been introduced in Victoria . Good for truckies I reckon .

About that trip in Peru on the bike . Was it a guided tour or did you do it off your own bat ?
