In a great many cities, hundreds of people ride bikes to work every day in New York, some bike riders have even formed a group called Bike for a Better City. They declare that if more people rode bikes to work, there would be fewer automobiles in the downtown part of the city and so less dirty air from car engines. For several years, this group had been trying to get the city government to help bike riders. For example, they want the city to draw special lanes(车道) for bikes on some of the main streets, because when bike riders must use the same lanes as cars there are accidents.
