Even if it weren’t for the car turning itself off, the car could overheat idling in the heat. Hybrids are not immune from that. I own one and had it happen while idling because my kid was napping and I stayed in the car with him in the driveway of the house. I was in the car, and noticed the AC suddenly got hot. I turned the car off and noticed the pool of coolant under the car. I woke up the kid, and went inside and ordered a radiator (which was a bitch to install btw). It’s incredibly negligent to leave your kids in a running car on a hot day. Also, someone could just come in and steal the running car with the kids in it. I hope they throw the book at her tbh.
