I think the combination of ideas that Silicon Valley is inching us towards is essentially what Personal Rapid Transit has always been. Electric cars are about eliminating the issue of pollution. The idea of ridesharing is to eliminate the maintenance, debt, and storage costs of owning a car. Self-driving cars are about eliminating the accidents and wasted time spent driving. Hyperloop is about using up less valuable surface space just for transportation, and hiding the ugliness of roads underground. Personal Rapid Transit has been able to accomplish literally all those goals since its inception. Each pod is autonomous, on-demand, driverless, and electric. It can be either on a hanging monorail, or undergound, to avoid wasting valuable surface space. And it doesn't require miles of ugly gray asphalt.
