Anyone who lives on the Upper West Side of Manhattan knows what it's like to walk across Broadway when the sign says WALK and then narrowly escape being hit by a delivery guy coming through on a bicycle. Or riding the wrong way down a one-way street.
There's a simple explanation. The delivery guys have been given the right at any time to regard themselves as either cyclists or a pedestrians. When the traffic light is green, they regard themselves as vehicles and ride. When the light is red they define themselves as a pedestrian who just happens to have wheels. They can choose whatever is advantageous at any time. Who can blame them? Life is short and they need the money.
I am reminded of this when I read rumors that some of the investment banks want to give up their bank holding company status now that their funding crisis is over.
