Self-driving cars, also known as autonomous vehicles (AVs), are cars that can drive themselves using sensors and cameras to detect their surroundings and make decisions about where to go and how to avoid obstacles. While the technology is still in its early stages, many companies are working on AVs and it is expected that they will become more common in the coming years. Potential benefits of AVs include improved safety, efficiency, and convenience, such as reducing the number of accidents caused by human error, improving traffic flow, and providing transportation for people who cannot drive. However, there are also concerns about safety and privacy that need to be addressed as AVs become more widespread.
