Self-Driving Cars

Imagine a car that drives itself! Self-driving cars use cameras, radar, and computers to see the road and make decisions. They can stop at red lights, avoid obstacles, and follow traffic rules. Many companies are working to make self-driving cars safe for everyone.

How They Work

Self-driving cars have sensors all around them that act like eyes and ears. Cameras see traffic lights and road signs. Radar measures how far away other cars are. A powerful computer puts all this information together and decides when to speed up, slow down, or turn.

The Road Ahead

Self-driving cars are already being tested in some cities. Robotaxis give rides to passengers without a human driver. But there are still challenges to solve, like driving in bad weather. Many experts believe self-driving cars will be common within the next 10 to 20 years.

Fun Facts

• Self-driving cars can see in all directions at once, something human drivers can't do.
• Google's self-driving car project started in 2009 and has driven millions of miles.
• Some self-driving cars use a spinning laser on the roof called LIDAR to see the world in 3D.

Did You Know?

The first self-driving car was built in the 1980s by a university in Germany. It could drive on the highway, but it needed a big van full of computers following behind it to work!
