Q: You are sitting behind the wheel in a car keeping a constant speed,
on your left side there is an abyss.

On your right side you have a fire engine and it keeps the same speed
as you.

In front of you runs a pig, larger than your car.

A helicopter is following you, at ground level.

Both the helicopter and the pig are keeping the same speed as you.

What will you need to do to be able to stop?

A: Get out of the car, step down from the merry-go-round and leave your
seat to someone younger. A merry-go-round is primarily for small
children.
