You step into the crosswalk and for ten seconds the cars stop for you. The crosswalk is the only place in the city where the pedestrian has more power than the machine. The car weighs four thousand pounds and the car can go sixty miles an hour and the car stops because you stepped off the curb and the stepping off the curb is the act of faith and the white lines on the pavement are the contract and the contract says the machine will yield to the body and the body trusts the contract even though the body has seen the contract broken a thousand times. You step into the crosswalk anyway because the alternative is never crossing the street and never crossing the street is not living in a city. It is being trapped by one.

The Abbey Road crosswalk became the most famous pedestrian crossing in the world because four men walked across it on August 8 1969 and a photographer stood on a ladder and took six photographs and one of the photographs became the cover of an album and the album was the last thing the four men made together that felt like the four of them still belonged in the same room. John was in white. Ringo was in black. George was in denim. Paul was barefoot. The crosswalk did not know it was being photographed. The crosswalk was just a crosswalk on a street in St John's Wood and the crosswalk is still there and tourists stand in the middle of traffic to recreate the photograph and the cars honk and the tourists do not care because the crosswalk is a pilgrimage site and the pilgrimage requires stopping traffic.

On March 7 1965 six hundred people began to walk across the Edmund Pettus Bridge in Selma Alabama and the walk was a crosswalk that lasted three miles and the police met them at the other end with tear gas and clubs and horses. The crosswalk became Bloody Sunday. John Lewis was twenty five years old and he walked at the front and the police fractured his skull and he got up and kept walking. The crosswalk at Selma was not about crossing a bridge. The crosswalk was about crossing the line between what the country said it was and what the country actually was. The white lines on the bridge were the same as the white lines on any street and the white lines meant you have the right to cross and the right was supposed to be guaranteed and the guarantee was a lie and the lie was exposed on television and the television changed the law.

In Tokyo the Shibuya crossing moves three thousand people in a single light change. The light turns and the crowd steps off the curb from every direction at once and the crowd crosses itself like a braid and nobody collides because the crowd knows how to move and the knowing is not taught and the knowing is not planned. The knowing is the city in your body. You learn to cross Shibuya by crossing Shibuya. The crossing is the lesson. Three thousand people trusting three thousand strangers to not walk into them and the trust holds every sixty seconds all day every day. The crosswalk at Shibuya is the largest act of daily cooperation in the world and nobody calls it cooperation. Everybody calls it crossing the street.

You stand at the crosswalk and the light says walk and you walk and the walking is the most ordinary thing in the world and the most extraordinary because the walking means the city agreed to stop for you. The city with its trucks and its taxis and its buses and its ambulances agreed to stop because you pressed a button and the button told the light and the light told the cars and the cars stopped and you crossed. The crosswalk is a negotiation between the fragile and the powerful and the negotiation happens a million times a day and most of the time the fragile wins. That is the miracle of the crosswalk. The soft thing crosses. The hard thing waits.
