On Monday, Department of Transportation Commissioner Janette Sadik-Khan spent an hour with Nancy Gruskin, whose husband had been killed by a "reckless bicyclist." The cause of death was unclear, as was the response from the city: A form letter addressed to Gruskin' dead husband, Stuart, signed by Sadik-Kahn. Eventually Gruskin got to share her feelings with the Transpo Commish. Among her requests was that the department begin tracking the number of bike-on-pedestrian accidents and fatalities, a statistic not currently collected. But her ultimate point was that the city is maybe a little too top gear in its embrace of the bicycle.

On Tuesday, Mayor Bloomberg gave a speech to the Clinton Global Initiative about his foundation's efforts to curb traffic fatalities. As the mayor pointed out, there are currently 1.2 million people killed on the road a year, more than the population of Dallas. With those numbers steadily on the rise, particularly in the developing world, traffic fatalities are on pace to surpass HIV/AIDS, tuberculosis, and lung cancer as the fifth deadliest thing on the planet by 2030.

On Wednesday, Sadik-Khan came to Union Square to inaugurate the latest re-engineering of Broadway, with more seating and different traffic patterns, and--you guessed it--more bike lanes.

UPDATE: One more. On Thursday, blogger Felix Salmon noticed a baby in its basket blocking one such bike lane on Grand Street in Chinatown.
