Brad Templeton has written up several articles about the advantages of robotic cars for revamping the transportation system.
Brad's robocar mainpage.
Brad looks at the myth of green public transit. Note: public transit can be far more energy efficient in places like asia where there is very high density on the buses and trains.
In Japan, they have pushers to pack more people onto the trains.
Brad also has calculations which show that while agriculture remains an oil and energy intensive business we do not get great overall energy savings by going to walking and human powered biycle riding
Robocar only zones would allow for an effective and safe transition to lighter vehicles like electric bikes and trikes.
