As I stepped into the house, the car reported ‘The rear driver side door has been left open’ on my phone. Well, it was open for a minute or two but I’m sure I closed it, I thought. I popped my head into the open garage door. Yup, it’s closed.
But 16 mins later the message came again, and I went and took a closer look.
Sure enough: the car was right. The door was ostensibly ‘closed’, but not latched properly (firmly). So to the car, the door was open.
