What do we do with a car and i need four reasons

We use cars to get to places - cars are the most effective way of short to medium distance transport and are used by 86% of Americas.

We use cars to calm down - Nothing is better when you are about to go into a rage than going for a long drive with the stereo up and nothing but you and your thoughts.

We use cars to live in - Some people fall on hard times and have to live in their cars for a while. It's more common than you might think.

We use cars to transport supplies - People use cars and other vehicles to carry things to far away places. 

Hope this helped. Have a great day!
