How often does this happen? It has happened in our town twice that I know of. It happened to my wife today while we were at one of the borg's. She came out of the store before me and went up to a similar looking black F150 that was parked across the isle from my truck. She hit the unlock button, it clicked and she open the door and got in. She did not crank the truck so we don't know if it would have. She realized her mistake, looked around and saw our's behind her. She was slightly embarrassed.
On the other time, a woman came out of a store and clicked her remote on a truck that looked identical to hers, it opened, she climbed in and started it up, then drove home, not realizing it was not her vehicle. She did not know anything was wrong until the police called her. They (the other vehicle owner), saw her truck and used her plates to have the cops locate her. This story made the front page of the papers.
I wonder how many other instances this has occurred. Mighty strange that it happened in the same town.
