[PyGame] pygame.draw.rect function stretches across the screen instead of moving

[BubblesTheGiraffe]

The title basically says it all, I'm currently getting started with pygame and whenever I use the draw rect function and try to move the rectangle it stretches instead. I put comments in my code wherever code related to the rectangles is.

[python]
import pygame
import time
import random

pygame.init()

car_width = 99
    
display_width = 800
display_height = 600

black = (0,0,0)
white = (255,255,255)
red = (255,0,0)
blue = (0,0,255)
green = (0,255,0)
dark_green = (0,150,0)
    
    
gameDisplay = pygame.display.set_mode((display_width,display_height))
pygame.display.set_caption("A bit racey")
clock = pygame.time.Clock()

carImg = pygame.image.load("racecar.png")
carImg = pygame.transform.scale(carImg, (100, 90))
#--------------------------------------------------------------------  
def things(thingx, thingy, thingw, thingh, color):
    pygame.draw.rect(gameDisplay, color, [thingx, thingy, thingw, thingy])
#--------------------------------------------------------------------
def text_objects(text, font, color):
    textSurface = font.render(text, True, color)
    return textSurface, textSurface.get_rect()
 
def crash():
    message_display("You Crashed!")

def message_display(text):
    largeText = pygame.font.Font("freesansbold.ttf" ,115)
    TextSurf, TextRect = text_objects(text, largeText, red)
    TextRect.center = ((display_width/2), (display_height/2))
    gameDisplay.blit(TextSurf, TextRect)

    pygame.display.update()

    time.sleep(2)

    game_loop()

def car(x,y):

    gameDisplay.blit(carImg,(x,y))
    return
