Google cars have been spotted driving themselves on Highway 1 between San Francisco and Los Angeles. The Toyota Prius cars that Google uses has a funnel cylinder on the roof and the person at the wheel was not actually driving.
The self-driving car is a Google project that uses artificial-intelligence software that has the ability to sense anything near the car and mimic decisions that are made by a human driver.
About seven test cars have driven 1,000 miles without human intervention and more than 140,000 miles with some form of human control. One of the cars even drove down Lombard Street in San Francisco. The self-driving cars are a project by Sebastian Thrun, the co-inventor of Google Street View and a director at the Stanford Artificial Intelligence Lab.
