There was (assume there still is) a small solar powered exhaust fan that you put on a window and is locked in when the window is rolled up.
Good to lower the temps in a sitting car.
As far as children are concerned, I simply have no solution to morons who don’t know they have THEIR OWN CHILD in the back seat of the car they are driving. We have reached the point of reductio ad absurdum when we have to design complicated mechanical devices to stop parents from killing the children they forget they have.
Sometimes the parents of young children are really under-slept. My son was the kind of kid who woke up several times a night and woke us up also. It was really hard to get proper amount of sleep and your attention may have huge gaps when you are in this condition.

yep, lotz to choose from out there. But these cannot lower temps below the outside ambient.
