How does a self-driving car navigate complex traffic situations?

A self-driving car uses sensors and smart thinking to move safely through busy roads, just like a kid learning to ride a bike in a crowded park.

Imagine you're playing a game where you have to follow the rules of the road, like stopping at red lights and letting other cars go first. A self-driving car has sensors that act like eyes and ears, watching what's happening around it: other cars, pedestrians, traffic signs, and even the weather.

The car also has a special kind of brain called software, which helps it make decisions, just like you decide to go left or right when riding your bike. If a pedestrian suddenly steps into the street, the car's software quickly says, “Stop!” and the car slows down or stops, just like you would.

Sometimes, the car has to choose between two good options, like changing lanes or waiting for a gap in traffic, it’s like deciding whether to take the shortest path or wait for a bigger space. It uses data from its sensors and past experiences to pick the best move most of the time.
