Pressure is mounting to arrest climate change, so it's hardly surprising that people around the world are being urged to use public transportation. After all, an overall strategy that includes getting people to give up their trucks and cars to use electric trolley buses, tramways and rail can help make a real dent in pollution, traffic congestion and greenhouse gas emissions. But try telling that to Australians living in the outback, long miles from the nearest bus station. Even most Japanese, who have access to some of the world's best high-speed rail links and urban mass transit, own some type of private vehicle.
