STEP 16: We can set up the collision event to tell us if we've hit a car.
- First we need to remove some code from the collision event. Delete the two lines of code that are there!
- Go to and drag out Get Image Name so that it's indented inside the collision event.
- Change my_var to image and change sprite to hit_sprite.
- The variable image will now store the image label of any sprite the turtle touches.
