You might look at a car and suddenly notice something strange.
The steering wheel is turning, but nobody is touching it.

You start wondering how the car knows where to go.
How can it see the road, the lines, and the other cars?

It feels like the car is making decisions on its own.
But cars are not alive, so how can that be possible?

You begin to discover that the car is constantly watching, measuring, and reacting.
And little by little, it becomes clear how a car can drive without a human driver.
