While Parisians are starting to complain that "an invasion of noisy scooters and motorcycles and a rise in accidents involving pedestrian and motorcyclists" is one of the "unintended consequences" of Mayor Bertrand Delanoe’s traffic reduction policies, "Gridlock" Sam Schwartz’s consulting firm just issued a report claiming that New York City could better meet its long-term sustainability goals by adding more scooters to the traffic mix. Commissioned for Piaggio, the Italian manufacturer of Vespa scooters, the study says:

Data from a new traffic model released
today demonstrates that the nation’s largest city could significantly
reduce carbon dioxide (CO2) emissions, a key factor in the global
warming debate, and reduce fuel consumption while saving a great deal
of time lost to congestion by simply incorporating more motor scooters
into the commuting vehicle mix.

By shifting the daytime vehicle mix to 80 percent cars / 20 percent scooters, the following would result annually: 

• A
  total decrease in delay of more than 4.6 million hours per year – which
  translates to time savings of nearly 100 working hours per person
• A reduction in carbon dioxide (CO2) emissions by over 26,000 tons (52,000,000-pounds) per year
• A decrease in fuel consumption by over 2.5 million gallons per year
• A total savings for New York City of more than $122 million per year in fuel and labor productivity.
