Operating an automobile usually requires fossil fuels, and fossil fuel pollution can cause asthma and lung problems, especially for children and the elderly. Given these facts, a possible downside of driving a car is among the following options:
- slow and inefficient
 - more asthma in children
 - split ends
 - greying hair
 - Plant growth is reduced
 - decreases its bodily water
 - balding
 - Greenhouse gasses
