Google driverless car
 
I'm supper excited about the new Google Driverless Car. I'm really thinking about making it my new car, if it ever come available in my state.
The Google driverless car is a project by Google that involves developing technology for driverless cars. The project is currently being led by Google engineer Sebastian Thrun, director of the Stanford Artificial Intelligence Laboratory and co-inventor of Google Street View. Thrun's team at Stanford created the robotic vehicle Stanley which won the 2005 DARPA Grand Challenge and its US$2 million prize from the United States Department of Defense.[2] The team developing the system consisted of 15 engineers working for Google, including Chris Urmson, Mike Montemerlo, and Anthony Levandowski who had worked on the DARPA Grand and Urban Challenges.
The U.S. state of Nevada passed a law on June 29, 2011 permitting the operation of driverless cars in Nevada. Google had been lobbying for driverless car laws. The Nevada law went into effect on March 1, 2012, and the Nevada Department of Motor Vehicles issued the first license for a self-driven car in May 2012. The license was issued to a Toyota Prius modified with Google's experimental driverless technology. As of April 2012, Florida became the second state to allow the testing of driverless cars on public roads.  California became the third state to legalize the use of self-driven cars for testing purposes as of Septemeber 2012 when Governor Jerry Brown signed the bill into law at Google HQ in Mountain View.
The project team has equipped a test fleet of at least ten vehicles, consisting of six Toyota Prius, an Audi TT, and three Lexus RX450h each accompanied in the driver's seat by one of a dozen drivers with unblemished driving records and in the passenger seat by one of Google's engineers. The car has traversed San Francisco's Lombard Street, famed for its steep hairpin turns and through city traffic. The vehicles have driven over the Golden Gate Bridge and on the Pacific Coast Highway, and have circled Lake Tahoe.[3] The system drives at the speed limit it has stored on its maps and maintains its distance from other vehicles using its system of sensors. The system provides an override that allows a human driver to take control of the car by stepping on the brake or turning the wheel, similar to cruise control systems already found in many cars today.
In August 2011, a human-controlled Google driverless car was involved in the project's first crash near Google headquarters in Mountain View, CA. Google has stated that the car was being driven manually at the time of the accident. A second incident involved a Google driverless car being rear-ended while stopped at a stoplight.
On March 28, 2012, Google posted a YouTube video showing a Morgan Hill, California resident, Steve Mahan being taken on a ride in its self-driving Toyota Prius. In the video, Mahan states "Ninety-five percent of my vision is gone, I'm well past legally blind". In the description of the YouTube video, it is noted that the carefully programmed route takes him from his home to a drive-through restaurant, then to the dry cleaning shop, and finally back home.
In August 2012, the team announced that they have completed over 300,000 autonomous-driving miles (500 000 km) accident-free, typically have about a dozen cars on the road at any given time, and are starting to test them with single drivers instead of in pairs.] Four U.S. states have passed laws permitting driverless cars as of September 2012: Nevada, Florida, Texas and California
