Self driving cars can drive themselves. if you think driverless cars exist only in the minds of science fiction writers, then think again. They are being tested on our roads now. Drivers are present we assume to take over, but road trials have been carried out on self driving cars that need no human intervention. Some claim them to be safer than regular cars because most accidents are caused by human error.Self-Driving Car Firms such as Toyota, Audi, and Hitachi are just examples of car manufacturing and or design companies that seem to have been looking at driverless cars. Another with its own version of the driverless car is Google. No admission has been publicly about this, but Google seems to be looking at such vehicles. We believe them when they state that, and accept that the day will come when cars will not require drivers.Hitachi Lexus has developed a car known as the Ropits (Robot for Personal Intelligent Transport System) that is claimed to be suitable for disabled drivers and the elderly. There is no claim for it to be a self driving car. This is common with all such cars. Perhaps for legal reasons, but nobody is claiming to have developed a car that can drive itself, even though it can.The Ropits has a roof-mounted camera with a 360 degree view, and systems that can detect traffic light signals from over 150 yards away. The vehicle also knows its orientation in the road and is distance from other cars when overtaking. However, although it may be able to drive itself when needed, Lexus is not claiming this and states that a driver must be present to take over manual control when needed. The company must do this for legal reasons.Google Driverless Cars Google has been testing cars such as this on roads in Nevada and California. It has been doing so on public highways with good results. Cameras, radar and lasers have been used to establish the location of other cars in the vicinity, and Google maps and GPS have been used for navigation.Google cars have recognized the location of pedestrians, and have stopped to let them cross the road, and have also been able to recognize and respond to traffic light signals. Naturally, no company has ever claimed to have developed a self-driving car, although some appear to have built working models and tested them on the nations road system.It is believed that self-driving cars would reduce the number of annual road accidents and fatalities. This is because they work to a set of rules that are not subject to human influence or incompetence. Future car technology will be partially focused on cars that need no human drivers, but are controlled by servo motors that take signals from radar, sonar and GPS.GPS and Self Driving Cars is not inconceivable that one day all cars will be fitted with GPS and their signals will be integrated to ensure that no two vehicles can occupy the same GPS coordinates. This will prevent collisions. Such systems would work via a system of motors, brakes and predictive analysis of the position of each vehicle at any specific moment in time.Communication between self driving cars and the environment around them will enable a prediction to be made on the basis of position, direction and speed. Ultimately such predictions could not only prevent two vehicles occupying the same space and time, but also a vehicle and an inanimate object such as a wall or a tree!Self driving cars will come. And the driverless cars of the future will help to prevent collisions, deaths and issuance claims. Perhaps one day car insurance will be made redundant by such technology. Now isn't that a nice thought More Information. Driverless cars and self driving car technology will soon become common. For now, however, visit the Benton Nissan website for information on the best of today's auto technology.
