Question

why are streamlined cars used specifically for f1 racing?

Answer 1

streamlined shapes reduce air resistance this increasing the speed

Answer 2

Now for racecars aerodynamic downforce is of a greater importance than drag, this does not mean that drag can be left aside, simply it comes secondary. So far, I have explained briefly what aerodynamics is and which forces are generated due to the airflow, and everyone has experienced firsthand the aerodynamic drag so it is easier to understand that one.
