Car Parts

My son and I got into a car and he first said, "I like this car. It is dirty like ours." That's nice to hear for everyone involved. Then he puzzled over something and finally asked, "What is this for?" He was pointing to the handle that rolls down the window. Are manual windows that rare? He was ecstatic to find out that I couldn't lock his window controls. He spent the trip rolling his window up and down.
