Last year the state of Nevada passed a law, making it legal cars drive themselves in Nevada. As of March 1 2012, researchers may apply for a special license, allowing them to test the robotic vehicles on open roads.
To mark these cars, they will be given a red license plate.
Once the testing is completed, they will then get a neon green license plate. Testing could take several years.
Shown here is Johnny Cab, the robotic taxi from the movie Total Recall.
Woah, robot cars are coming.
