I got a Magic Door Screen at a discount store for $5. It has 2 panels and magnets along one edge of each for easy entry/exit when used as a screen for a door. Instead I use a panel on each side of the RAV4. I attach the magnet side along the bottom of the driver and rear windows on that side, stretch it up over the open doors, shut the rear door with the non-magnet portion of the screen inside, then smooth the rest of the panel along and over the open driver's door, then tuck the non-magnet portion inside and close the door. Repeat on other side of the car, except after closing that rear door, I sit in the front passenger seat, pull the screen inside over the door top, then close the door on the screen. I can tweak the magnet portion from within through the open window if needed. I usually roll the windows up, leaving no room for a person's hand to reach inside, but enough for ventilation. More often, I do the passenger side first since there is usually a cooler and tons of stuff in that seat, then enter thru the driver's door and pull the screen over its top and close the door. I tend to keep the driver's seat empty in case I need to make a fast get away, LOL.
