It's summer. It's stinking hot. And for any silly person who leaves their pets (or any imbecile who leaves their kids) inside a parked car, watch this video where a doctor traps himself inside a parked car to see how how it gets. Even with all four windows cracked down a bit, the car temperature reaches 117 degrees in only 30 minutes. And no. Even if you leave your pet inside for just five minutes, the temperature already spikes and becomes miserable.
The best way to raise an engine's temperature to optimal levels is to drive it almost immediately after startup; according to a study by the Ontario Ministry of Transportation, a car driven for 12 minutes in 14-degree-Fahrenheit weather will achieve the same temperature as one that idles for 30 minutes.
