Car ban fails to curb air pollution in Mexico City

The article is about Mexico "car ban" policy, instituted to limit the amount of pollution put into the air by vehicles. Despite the policy's name, it is not an ban on cars so much as it is a restriction of the times in which citizens and corporations can operate their vehicles. When the car ban policy was first proposed and instituted scientists had predicted that vehicle emissions would be reduced by 15%, just by limiting driving throughout the weekend. Unfortunately, new information has shown that the ban has done nothing to reduce air pollutants, or the rate at which they are being put into the air.
