Some people say they have an answer to the problems of car crowding and pollution. In many cities, hundreds of people ride bikes to work every day. In New York City, some bike riders have even       a group: Bike for a Better City. They say if       people rode bikes to work, there would be fewer cars and less dirty air.
For several years this group has tried to help bike riders. They want to have special roads for bikes only because when bike riders must use the same roads       cars, there may be accidents.  Some people for a better city feel if there were bike roads, more people would use bikes.
But     bike roads have been ready yet. Not everyone thinks it is a good      .Drivers don't like it, and some shop owners don't     . And most people living       _ far from the city to have to travel by bike. Still,       has been done about it. On Saturdays and Sundays, the largest open park in New York is          to cars, and the roads may be used by bikes only, but the group still says this is not enough and goes on fighting        bike roads.
