my dad always leave the windows open almost half inch in summers but i never understood the logic behind that. he used to leave it open even when the car was parked at home in summers. i understood it when i took dad's car to uni(i go to uni on my bike) , it was parked there for around 6 hours, when i came back and sit inside it, it was seriously like a tandoor. i immediately opened the windows to make it normal. it was hard to breathe even.
