text: Part of the explanation certainly lies in the recession, because cash-strapped Americans could not afford new cars, and the unemployed weren't going to work anyway. The next few years would be telling. Transportation is the second largest source of America's emissions,just behind power plants. Ford and Mercedes are already rebranding themselves "mobility" companies with a broader product range beyond the personal vechicle. People who stopped car commuting as a result of the recession may find less reason to resume the habit. A car is just means of getting from A to B when BART doesnt' work.    Kids and young adults that go down wrong paths can change. After school or extracurricular can help that. I think that students having to participate in a extracurricular activity is one of the best things a school can do. Even if its just a homework club. It will keep them busy and will help them exceed academically. It will help build strong relationships with there peers and teachers. Students that participate in extracurricular will exceed academy and will not go down a path of illegal activity.
