Cars without Drivers

We live in a modern world with
1
constant technological innovation.
These new ideas often raise difficult
moral questions. “Driverless” cars,
2
which drive their passengers around
automatically, are a good example.
When the technology first appeared,
it was just one more amazing modern
invention. Now, four U.S. states allow
driverless cars on certain roads.
Nevada, Florida, California, and People in a driverless car
Michigan have all passed laws that TK
permit them. Several cities in Belgium, France, and Italy are also planning for them.
Do you feel safe knowing that the cars around you might not have drivers? In a
dangerous situation, a driver must react instantly. A car without a driver has only its
3
computer program.
So what happens if a child runs in front of a driverless car? The child’s life is in
4
danger, and the situation requires an instant response. Will the driverless car change
direction and put its passengers in danger? Or will it continue toward the child because
that reduces the risk to the car’s passengers? If the machine makes the morally wrong
choice, who is to blame . . . the car company or the helpless passenger?

1 innovation: the process of developing new and improved ideas, methods, and products
2 moral: related to what is right or wrong
3 react: speak or move when something happens
4 require: need
