How Do Self-Driving Cars See the World?

Self-driving cars use special eyes called sensors to see the world around them, just like we do with our eyes. These sensors can detect things like other cars, people walking, and even traffic lights. Inside the car is a brain, think of it as a super-smart computer, that puts all these pieces together to understand where everything is and what’s going on. It helps the car drive safely without anyone inside telling it what to do.

How They See

The sensors work like cameras, but they can see in the dark and through rain or snow too. Some use lasers to create a 3D map of the world around them, kind of like how you might trace your finger across something to understand its shape.
