>congestion-free and at higher speeds Neither of these has any chance of being true. Highways near any sort of metropolitan area, or near a spur leading to a metropolitan area, or even often near a connector leading to another major highway, are already massively congested. Autonomous automobiles making even more people want to use them will only make it that much worse. And even safe, self-driving cars operating outside of traffic can only travel at a fraction the speed of rail.
