If you have, what are you going to answer an 8-year-old kid when he asks: 'Why does the car move?'; Are you going to start explaining high school physics, mechanics, chemistry of combustion and the concept of friction. Or are you just going to say: 'Well, the car eats up gas, and that makes the engine move the wheels.'; Granted, the latter doesn't explain much about what a car is....
