In their view, that can help avoid panic, injury, or worse.AdvertisementAdvertisementEVs are well suited for this use case because they can run air conditioning from the battery while parked, without idling a gas engine. A visible message outside the vehicle can also reassure passersby that the pet inside is not in distress.What can I do?The video emphasized systems that both keep climate control running and display a clear notice outside the car.Some EVs already offer a feature along those lines.At the same time, the hosts were not saying pets should be left in vehicles for long periods, even if the system is well executed. Their point was that short errands are safer when the vehicle is designed for real-world use instead of forcing owners to improvise.AdvertisementAdvertisementWhether automakers label it "Pet Mode" or "Dog Mode," Out of Spec Reviews' demonstration argued that this should no longer be treated as a luxury feature. In a hotter world, keeping a parked car cool can be the difference between an ordinary stop and a deadly mistake.Get TCD's free newsletters for easy tips, smart advice, and a chance to earn $5,000 toward home upgrades.
