How do you drive a car?

insert the key into the keyhole and start the car...

check if there is fuel available in the tank...

while keeping the clutch pressed, shift gears...(if it is an automatic transmssion, you don't have to worry about clutch and gear)

slowly release clutch and press accelerator...

use the steering wheel for moving your car towards left or right...

basically

press the accerlerator to move forward, brake to stop/slow, and steering wheel to steer.
