Car Emissions

NPR's Philip Davis reports that beginning this year, 27 states and the District of Columbia have been required, under the Federal Clean Air Act, to begin tougher automobile emissions testing. The rules would require motorists to have their cars tested at centralized test sites, as opposed to the local gas station, where much of the testing is now done. Most of the states involved are upset with the requirement, arguing they don't want to spend the money to build new tests sites. And motorists are angry, because of added inconvenience.
