Which way is the bus below traveling?  To the left or to the right?

Pre-schoolers all over the United States were shown this picture and asked the same question.  90% gave the same answer. Try to figure it out and then check the answer after the break.

The bus is traveling to the left.

When asked, “Why do you think the bus is traveling to the left?”
They answered:  “Because you can’t see the door to get on the bus.”

Post your answer in the comments below! I am really curious how others do, as I totally flunked this test.
