When I worked in Mumbai it took me about two weeks to learn how to cross the street: just walk out into the traffic with your hand up, and everyone goes round you. Everyone ignores the lights, so you just need to take your chances. I got hit by mirrors a couple of times, but since everyone expects to see pedestrians in the road it generally works.

New York though... so often I'm crossing on green and there's some truck edging round the corner into my path, driver making eye contact, daring me to try to make him stop.
