Electric scooters may get a kick-start from an unusual source: The NYPD. Starting in January, four scooters will be added to the city's police motor fleet. Though their number hardly makes for a revolution, the Vectrix scooters (the first plug-in vehicles legal on any highway or road) are part of a larger mission to green the department. Already, it boasts a number of hybrid and flex-fuel cars.
We've covered Vectrix's stateside arrival in the past. An $11,000 price tag puts it out of the reach of most consumers, but if the NYPD test is successful, it may popularize the scooter enough to help bring down the cost. Meanwhile, the department insists long-term fuel savings will offset a higher price.—Abby Seiff
