Hmm -- is it a swimming pool for cars?
Ohh -- you probably mean a group of 2 to 5 people who ride to work in the same car together.

A car pool is formed when a group of people who work at or near the same location get together and take turns driving to and from work. It saves on gasoline and wear and tear on the cars (since individual cars are not driven as many miles per week).
