ok im at the lab at school and i look at the screen of the guy next to me and hes looking at big aluminum wings. i don tknow if i should tell him about the functionality of these things

 

Maybe his car didn't come with a back seat.

 

tell him those things are good for gas milage.

tell him to adjust it facing up, creating UP-Lifts, and make the car feels lighter on highway, less weight to push. hahahah

the engine don't have to work as hard, thus better on gas milage.
