(1) You are taking heat from the garage and moving much of it into the attic where an additional heat load is added to the ceiling making your air conditioner run harder and longer (i.e., many more KWHs consumed plus wear and tear on your AC).
(2) Many house fires begin in the garage and the open attic door will allow it to engulf the entire house once it moves into the attic. There are no walls in the attic.
My 2-cents ----- I would close the attic access completely, and leave the screen garage door open.

How many house fires have there ever been in TV, very, very few. I have a thermostat controlled attic exhaust fan, a vent in my attic stairs cover, and 3 vents on the bottom of my garage doors. When it's hot enough in the attic for the fan to come on there is a constant flow of air coming into the garage and out through the attic. I'm not too worried about a fire with that little vent in the door, catastrophic damage or injury is more likely from a tornado or hurricane than a fire. There was more damage from the 07 tornado than there will ever be from fires in TV.
