They were both entered into the DARPA Grand Challenge - a race for autonomous vehicles.
On the other hand, cities still have a density advantage that will make autonomous vehicles more economical.

Even without a debate over we really want our cars to drive themselves, autonomous vehicles keep gaining ground.
Consider, for instance, the possibility that autonomous vehicles will work well enough to replace a lot of inter-city rail.

Nevada has passed a law allowing autonomous vehicles to operate on its roads, and California is considering similar legislation.
There will be greater vulnerability with increasing numbers of intelligent systems creating more potential targets, from autonomous vehicles to smart grids.

The company is preparing to release an initial batch of autonomous vehicles, capable of speeds of up to 31 miles per hour, in 2014.
So will cities, suburbs, or exurbs be the winners from autonomous vehicles?

The real question is not our ability to technologically evolve autonomous vehicles.
The cars, sometimes known as autonomous vehicles, use technologies such as radar, global positioning and computer vision to operate independently of human input.
Sebastian Thrun, from Stanford University, burst into the headlines last year by winning a U.S. Defense Department race of autonomous vehicles through the desert.
Autonomous vehicles, such as the Google creations that have logged some 140, 000 miles on American roads, could make transport dramatically cheaper, safer and more efficient.
Founded by Andreas Raptopoulos, the company have ambitious plans to build a network of autonomous vehicles delivering food and aid to inaccessible areas in developing countries.
The momentum is gaining for autonomous vehicles to become a common form of transportation, even as the debate about their safety and utility continues on.

Instead of picturing autonomous vehicles as extensions of city subways, think of them as replacements that put a subway stop everywhere you want one to be, and at all times.
FORBES: Who Wins More From The Google Car: Cities or Suburbs?
Government regulation and legal liability could soon become bigger obstacles to the spread of autonomous vehicles than the technical challenges of making the systems reliable and cheap enough for mass-market vehicles.
This may not be fast enough to compete with the first models of autonomous vehicles, which will probably just be normal cars with computer brains and sensors strapped onto them (to put it in technical terms).
FORBES: Who Wins More From The Google Car: Cities or Suburbs?
At a recent industry conference, industry executives said that by 2020, they expected consumers will be able to buy vehicles that offer limited self-driving capability, and by 2025 fully autonomous vehicles could be available in significant numbers.
The sensors we use for the blind driver challenge vehicle are almost identical to the ones we use for autonomous vehicles, and we have used for this project many of the technologies we have developed for our autonomous cars for the 2007 DARPA Urban Challenge.
If significant numbers of autonomous vehicles are on the road, they could even be used collectively to control the flow of traffic, which might help minimize traffic jams, thereby decreasing commute times and avoiding all that stop-and-go traffic that wears down vehicles and it bad for the environment.

It will only be used for licensed autonomous test vehicles.

For one thing, Congress has decreed that by 2015, one-third of America's combat ground-vehicles must be autonomous.
Even when semi-autonomous driving capability is available on vehicles, the system will have operational limitations based on external factors such as weather and visibility of lane markings.

The focus of autonomous vehicle research is on developing intelligent vehicles, or artificial intelligence for cars in some sense, while the focus of the blind driver challenge vehicle is developing methods to convey a vast amount of information to the driver through nonvisual means, fast enough and accurately enough for safe driving.
Research is being done on autonomous braking technology, which can stop a car when other vehicles or obstacles get too close, and lane-keeping support, which applies a correcting force through the steering if the driver drifts out of their lane.
By adding in wireless communication, the vehicles in the platoon "mimic" the lead vehicle using Ricardo autonomous control - accelerating, braking and turning in exactly the same way as the leader.
