25. Motorcycles and City Traffic

In recent years, the number of motorcycles on city roads in china has been increasing. This is because they are a cheap of transportation for people in a country where motor cars are expensive for most families. In addition, motorcycles are convenient for driving and parking on crowded city streets.

However, motorcycles have disadvantages too. They pollute the atmosphere with smoke and noise. They are also a more dangerous from of transportation than motor cars, because the motorcycle is less stable and there is little protection for the driver in the case of an accident.

It seems to me that city governments should restrict the number of motorcycles allowed on the roads. This would limit the pollution they cause, but at the same time help to relieve traffic congestion. There should be a balance between the advantages and disadvantages of the motorcycle as a form of city transport.
