It's called PRT (personal rapid transit) and in my view, it's the one glimmer of hope in turning a century's worth of investment in automobile infrastructure from a liability into an asset. It's a fantastic idea that's gaining some limited traction in places like London Heathrow (http://www.ultraprt.com/prt/ http://www.ultraprt.com/prt/), where hopefully it can gain enough of a foothold to expand. Right now, PRT systems tend to use their own rights-of-way, but with the advent of true driverless cars, all that could change.
