    If you open a window and repeatedly open/close a door on the other side a few times, your car will have the same temperature inside as is on the outside

      If you have a hatchback, it’s even easier. Lean in, start the car, roll down the windows, walk around to the hatch. I don’t even bother doing more than one open and close anymore.

      No it won’t, the thermal mass of the car is way higher than a few of its volumes of air, and it’s still sitting in the sun too

        Dude, I’m talking about the air inside the car. Obviously you’re not cooling down the whole car, but you won’t have to sit in sweltering heat for multiple minutes.

          The thermal mass of the metal, rubber and plastics inside the car will continuously reheat any fresh air that is introduced to the inside. That’s why car air conditioners are so powerful, way more BTUs than your average window unit of a similar size.

            My guy. When you enter a car in the summer, the air is very hot and it takes a couple minutes to cool it down. When you replace the air first using the trick I mentioned, the air is much cooler, so you don’t sit in hot air for a couple of minutes. I’m not saying to do this instead of AC.

            How hard is it to understand this? Cooler air is cooler than hotter air. My god.
