“Ze Car, Ze Car.”
“My dear guests, I am Mr. Roarke, your host. Welcome to Autonomy Island.”
Yes, here on Autonomy Island, all of the cars are autonomous. Your adventure will be to ride and drive in a place without fear of a human running you over.
When will an automaker (or collective of automakers, or government, or Google) buy all the cars on an island (and perhaps rent the government), replace them with new autonomous vehicles, and see what happens … to safety, to travel behavior, etc?
This is the kind of real world laboratory experiment that would be highly useful to understand the implications, the unintended side effects, the bugs and so on of robotic cars.
For instance, take the US Virgin Islands. St. Croix has a population of about 50,000 people. If it follows general US patterns, it has about 33,000 light vehicles. For about $1B [Less than the cost of a single NFL stadium] all of the cars could be replaced with autonomous vehicles at about $33,000 each. [This might be a stretch, but that would be a typical mass production cost.]
The USVI collectively has between 10 and 20 auto fatalities annually. At a $9.1 million value of life, that is at least $91M per year. In 11 years, the experiment would pay for itself if in fact it eliminates fatal crashes the way autonomous vehicles are expected to, leave aside any other potential benefits.
The advantages of an island are that it is a closed system, it can be fully mapped, no one can drive on or off. The advantages of a real island with real people are the ability to see how these interactions might actually occur in use.
Autonomous vehicles interacting with only autonomous vehicles should be much easier to design than autonomous vehicles in mixed traffic, as the environment is less variable. People, animals, weather, and so on are still potential confounding factors, but should be simpler to manage than a person in a car.
