You have described my personal vision of a PRT-connected future even better than I have myself. What's so beautiful about it is that it takes a massive infrastructural liability -- a century of building our world around the automobile instead of around rail or other mass transit systems -- and turns it on its head. We get out of infrastructure jail free. Think of the time humans spend behind the wheel of a car today. How many hours a day? How many solid days of driving a year? How many man-years of humanity are wasted on fruitless idling in traffic? A society with autonomous personal transport becomes a measurably more productive one and likely a happier and more satisfied one as well.
