The Martian and the carThe Martian and the car These life forms rolling along roads in great These life forms rolling along roads in great
numbers. They were giving off thick clouds of numbers. They were giving off thick clouds of poisonous waste as they moved. Many of the poisonous waste as they moved. Many of the cars moved in the same direction. They cars moved in the same direction. They appeared to have a great deal of energy, some appeared to have a great deal of energy, some of them moved very quickly. When one of these of them moved very quickly. When one of these life forms stopped or slowed down, the others life forms stopped or slowed down, the others behind it responded. They slowed down and behind it responded. They slowed down and gave off a reddish light from the back, and gave off a reddish light from the back, and sometimes they would make honking noises. sometimes they would make honking noises. They would stop to feed on a liquid substance."They would stop to feed on a liquid substance."
