Is my Saturn supposed to run, shift, even drive without the key in the ignition?

What is your question?

The car runs without the key in the ignition. I discovered that by accident when I was in a hurry one day. I didn't realize it would drive like that, until I drove somewhere one day, and when I went to shut the car off and take the key out, the key was already out. I had put it in the console and forgot to put it in the ignition when I started driving.
