Dualmode: transportation´s future

In two or three decades, the predominant transportation system in much of the world will likely be dualmode transportation. We will use even more private cars but do it without our current problems by operating them in two distinct modes. We will drive them in the normal manner on the streets, and they will travel automatically at high speeds on special guideways with no driver and their motors shut off. These guideways can be of several different types, but all will carry electricity to power the vehicles. Trips of more than several miles will use the guideways rather than the highways. We will travel more safely, more cheaply, more quickly, less stressfully, and with neither gasoline nor pollution
