There could be downsides, however, to the busing cutbacks. If every formerly bused student begins walking to school, it’s an environmental win—but if too many of their parents decide to drive then instead, the overall carbon footprint can grow. Replacing buses with many more parent-driven cars can also increase safety risks: A 2002 report concluded students are 13 times safer on a school bus than in a passenger car, since buses have fewer accidents and withstand them better due to their size. And some students complain about the long morning hikes, particularly when the route contains a really big hill.

Passage Three

If you haven’t heard or seen anything about Road Rage in the last few month you’ve probably been avoiding the media. There have been countless stories about the new and scary phenomenon, considered a type of aggressive driving. You have more likely encountered aggressive driving and/or Road Rage recently if you drive at all.

While drunk driving remains a critical problem, the facts about aggressive driving are surely as disturbing. For instance, according to the National Highway Transportation Safety Association, 41,907 people died on the highway last year. Of those fatalities, the agency estimates that about two-thirds were caused at least in part by aggressive driving behavior.

Why is this phenomenon occurring more than ever now, and why is it something that seemed almost nonexistent a few short years ago? Experts have several theories, and all are probably partially correct. One suggestion is sheer to overcrowding. In the last decade, the number of cars on the roads has increased by more than 11 percents, and the number of miles driven has increased by 35 percent. However, the number of new road miles has only increase by 1 percent. That means more cars in the same amount of space; and the problem is magnified in urban areas. Also, people have less time and more things to do. With people working and trying to fit extra chores (
