In order to describe an elephant's size, our book compares elephants to cars. It says that elephants are as tall as three cars stacked on top of one another. What better way to see that than from a car? Watch this elephant walk right past this car. Also, listen to what one child says about its size right at the end.
Here's another video of an elephant walking by a family in a van. (Although I'm not sure about the "please tip the van" comment.)
