Push Button, Wait Anyway

From The New York Times:

For years, at thousands of New York City intersections, well-worn push buttons have offered harried walkers a rare promise of control over their pedestrian lives. The signs mounted above explained their purpose:

Wait for Walk Signal

Millions of dutiful city residents and tourists have pushed them over the years, thinking it would help speed them in their journeys. Many trusting souls might have believed they actually worked. Others, more cynical, might have suspected they were broken but pushed anyway, out of habit, or in the off chance they might bring a walk sign more quickly.

As it turns out, the cynics were right.

The city deactivated most of the pedestrian buttons long ago with the emergence of computer-controlled traffic signals, even as an unwitting public continued to push on, according to city Department of Transportation officials. More than 2,500 of the 3,250 walk buttons that still exist function essentially as mechanical placebos, city figures show. Any benefit from them is only imagined.

Why am I picturing a grinning George W. Bush, in New York for the convention come this August/September, blithely pushing away?
