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