You know you should never leave your pets and kids inside a parked car, even in winter. Watch this video where a doctor traps himself inside a parked car to see how hot it gets. Even with all four windows cracked down a bit, the car temperature reaches 47C in only 30 minutes.
No, even if you leave your pet inside for just five minutes, the temperature already spikes and becomes miserable. Veterinarian Dr Ernie Ward put himself through an experiment so none of us ever have to feel the misery of being trapped inside a car on a hot day. Temperatures can get 20C hotter inside the greenhouse trap of a vehicle, people! So don't ever do it. [Dr Ernie Ward via Daily Dot]
