Started car
 

This was a senior moment. Started car. Went back in house. left car running. Changed jacket (zipper broke). Key was in jacket. Put on new jacket. Went back to car (still running). Drove to destination. Turned engine off. Tried to lock car. Of course key was at home. Had no way to start car again. Wife had to bring me my key. Good thing it was a short trip from home. Have you heard of this one? Is this a flaw in the programming that you can drive your car without the key?
