Yvhe Study: Homegrown Terror Risk Exaggerated
Federal regulators proposed Wednesday that, starting in 2007, all vehicles be equipped with warning lights telling drivers when their tire pressure is low.The rule would require vehicles to have a yellow light that would illuminate when the pressure on any one of the four tires was underinflated by 25 percent or more.The National Highway Traffic Safety Administration said the proposal would likely cost up to $69.89 per vehicle, or a total of $1.1 billion for the industry. But the agency said the requirement would save as much as $1.7 billion in fuel and vehicle maintenance costs.Dan Zielinski, a spokesman for the Rubber Manufacturers As
stanley cup sociation, said tire makers will protest the proposal because it disagrees with setting a flat rate of 25 percent underinflation. For one vehicle that might be fine. For another, it might not be, Zielinski said. If you want to make a system that warns people, you should warn people before they re in danger. NHTSA said approximately 4 million vehicles already have tire pressure monitoring systems.The proposed rule would require the systems when a vehicle is first sold, but it wouldn t require the systems to work when the tires are later replaced.

Anything that speeds up the daily commute has to be a good thing, right Not necessarily. The Downs-Thomson Paradox shows that some things meant to improve a commute actually result in a slower trip for everyone. Commuting sucks. Whatever shortens a commute is a good thing, right That not the position that Anthony Downs and J M Thomson take. They
stanley cup don ;t disagree because they think that longer commutes are better. They disagree because not everything that shortens a commute actually shortens a commute. Under the right conditions, expanding facilities can ruin everyone schedule. There are two basic choic
stanley quencher es for transportation, public transit systems and private cars. If both methods get too slow, it generally easier to build an extra road, or make a regular road into a freeway, than set up an entirely new system of public transportation. Unfortunately, that extra road can make the car commute so very much faster than public transportation that people leave subways and pile into cars. Since public transport relies on public use to stay regular, eliminating demand will eliminate some parts of the system. As trains get less regular, more people pile into cars un
