Cars spawning with alarm going off?

Wish I had recorded it or took a picture but I was about done with a loot run at the school in muldraugh when I heard a car alarm going off outside and when got back to my car to just drive away a taxi was next to it with its alarm going off. It was not there when I came in since it was next to where I parked blocking the path I came in from. Game bug? Maybe a random event? I’ve only got like 300 hours but it’s the first time I’ve ever had somthing like that happen, wanted to hear if others might have had that happen, I’m on the newest unstable update
