An autonomous or self-driving car is a vehicle that is . It senses its environment using radar, GPS, computer vision, and other devices.
Advanced control systems interpret sensory information to identify navigation paths as well as obstacles and traffic signage. Autonomous cars can even , which can be useful in planning a navigation path.
Experiments with autonomic cars first appeared in historical records dating back to the 1920s. It wasn't until the 1980s, however, appeared in navigation labs on an international level.
One potential advantage that autonomous cars could , tailgating, rubbernecking and other forms of distracted or aggressive driving.
Another benefit is due to a reduced need for safety gaps and the ability to better manage traffic flow.
A higher speed limit and removal of constraints () are additional plusses to having autonomic cars on the road.
Some potential obstacles to using autonomous cars include the liability placed on the manufacturer of the device and/or software driving the vehicle, time needed to turn an existing fleet of vehicles from nonautonomous to autonomous, , and loss of privacy.
Also, current police and other pedestrian are not adapted to autonomous driving.
