I think a key difference is that you drive the car everyday. Even if you have no clue about the inner workings of the car, you have a direct, frequent, operating relationship with it. You understand its basic principles and functionality in a hands-on way (literally). If unseen defects are present in a car, they'd reveal themselves to you in short order. The same cannot be said for houses. You live in a house everyday, but you don't have a true working or operating relationship with it unless you're very handy (which many home buyers these days are not). The car has a direct input/output operating cycle that you control; the house does not. It's harder to suss defects out because the house doesn't 'run' on them per se. You only learn about the defects when the house fails in one way or another. That may be two days into the inspection period, or it may be two years after closing.
