text: Beginning from the late 1950s, the concept of the driverless car was already thought of. Now, the concept is beginning to come to fruition due to the advanced technology created. The most important bit of technology on the driverless car is the spinning sensor on the roof, also known as the LIDAR. The LIDAR is able "to form a constantly updating 3-D model of the car's surroundings." Without the LIDAR, the accuracy of the driverless car would be greatly reduced as the car would have no sense of its surroundings. Another technology that was greatly enhanced is the antilock brakes. In the 1980s, the antilock brakes "used speed sensors at the wheels" to monitor when the car was becoming out of control. Back then, the antilock brakes only had a sensor to monitor the wheel's speed. Now, the antilock brakes have become more advanced to the point that they are able to "detect and respond to the danger of out-of-control skids or rollovers." The antilock brakes have evolved from only having a sensor that monitors speed to sensors that can detect many dangerous conditions. The advancement of car technology greatly affects how safe and successful a driverless car may be. A driverless car would most likely not be able to work in the 1980s with the speed sensor as the antilock brakes. Now, the driverless car would be able to work very effectively as it combines a plethora of sensors and cameras to ensure safety. Speaking of safety, the driverless cars all have a safety feature that guarantees almost the maximum safety potential.
