I don't believe cars actually function via mechanical forces. It is the car's machine spirit which moves the vehicle.

If my car's timing belt gets broken or the alternator is malfunctioning, that doesn't stop the car. Clearly the machine spirit is strong enough to move the car even without a timing belt. However, the car's machine spirit will become angry and run sporadically, or lethargic at my poor maintenance and unwilling to start. The machine's spirit shall not be appeased until I take it to a proper mechanic so that he may assuage it with the holy rites and coax it to run again.

Those heretics who do not believe that cars have souls are simply making the Radio Fallacy. Fortunately I have seen the truth. Praise the Omnissiah!
