The technology that enables the development of self-driving cars includes a combination of sensor technology, machine learning, and artificial intelligence (AI). Sensors, such as lidar and cameras, collect real-time data about the vehicle's surroundings, allowing it to detect obstacles and navigate. Machine learning algorithms process this data to understand driving environments and make decisions while on the road. Many self-driving systems also rely on GPS for navigation and trajectory planning. The integration of these technologies is essential for achieving safe and reliable autonomous driving.
