I guess you didn't read the article: ""We live in a world designed around cars. Because world population has grown five-fold during the age of cars, we will be stuck with their legacy in roads and low-density metro configurations for at least the next century. This realization is a difficult one. I set out to start a company that could radically transform transportation. But neither the physics nor economics work out, and in fact will not work out until population density is much higher. It is the ubiquity of roads, more than the greatness of cars that is difficult to defeat. And so, the future of transportation is, perhaps disappointingly, simply better cars. Our abstract criterion for the perfect transportation system is one that is fast, ubiquitous, has on-demand departure, and is quiet, private, and safe. The solution to all of these is a self-driving car. It is clear that a maglev based personal rapid transit elevated track system should not be pursued as a business.""
