It happened to me once when I told my mother to come and pick me up at the main bus station. I sat in someone's car and they were shocked and then told me it's ok and that it happens. Since then I always look at the registration first.
I remember this guy came in my car while i was in tha McDonald's parking lot and he was like oh **** my bad bruh. I moved outta that city. Never again.
I actually got into the wrong car accidently and someone was in there
It was a black car similiar build to my mothers . She was parked in my moms usual parking space when she picked me up from school.
I remember going to the mall with my friends once during lunch break in college. I had to go back to the car so my friend gave her keys. I went to the car and put the key in but it wouldn't unlock (the sensor thingies weren't around then). 10 minutes later I realized it was the wrong car on the wrong floor of the car park
