A car and a key

Who do you think is smarter, my car or me?

It was one of those days. I parked, picked up my computer bag, locked the car doors, closed the door, and walked away. I was two steps from the car when I heard a noise, a beeping sound.

Hmm... I wonder where that is coming from. The noise persisted, and I turned around. Two steps back to the car, I reached out and opened the door to see the message "Key detected in vehicle". Really? I was sure I had the key in my hand. I looked, and my hand was empty. Oops! Luckily my car is smart enough to unlock the doors if the key is still in the car. I'm very glad that my car was smarter than me this morning.
