No, I'm comparing our vast amount of knowledge and self-help for our own bodies vs vehicles. Humans have many temporary ailments that are either self-limiting, or simple to treat. Colds, flus, headaches, sprains, nausea, diarrhea. OTC meds and devices.
No such thing for a car: if there's a problem, there's a problem. Chicken soup and rest won't change a damn thing for a car, they don't self-repair like humans. That's why mechanics charge at least $65/hour. They do earn that, though. Anyone who's gone to a physician to be told they have the flu, drink fluids and rest, and gets a $100 bill for that 15 minutes knows exactly what I'm saying.
