I once turned the key, it unlocked, I sat in the car and tried to start the car, only to realize it wasn't my car. It wasn't even the same make or model. To this day I do not know how the door unlocked.

lol in college during winter semester I once scraped the snow off of someone elses window one morning. Didn't notice until I saw the stuff inside the car😳

Yeah. Except i just kept pushing the button on the key and was confused as to why the doors weren't unlocking.

When I was younger, one car looked much like another to me, and I remember going shopping with some friends in a "green car" and when we went back to the parking lot as we walked by a green car, I opened the back door and got in ! The others stared at me and said, "why are you in that car ?" and pointed out the actual car a few slots down. I was lucky the owner didn't see me, and quickly got out ! They still tease me about that ("and this is the car we came in !"). 😂

ive done it in other places, start opening the door to my place only to realize im opening someone elses door

Yes and jumped in the back of incorrect cars while waiting for a lift.
