I had no trouble at all walking around in Australia and New Zealand, however London is a different story. I get very disoriented there and have had a few near misses. I figured out why. In most places, cars parked on the side of the road tend to face the direction of traffic flow. In London I saw that cars park any which way on both sides of the street. Not uncommon to see two cars facing each other on the same side of the street. I apparently use parked cars as visual cues to which way traffic is flowing and when I encounter a car parked in the wrong direction, I make a wrong determination of traffic flow and look in the wrong direction before stepping off the curb. The fact that all the crossings have "Look right-->" painted on the ground doesn't seem to help me. :-)
