That's a pretty good way to look at it. I'm not saying we should neglect our cars, but as in my case, there might be higher priorities than squeaky hinges. Yes, I'll get to the hinges, but it really doesn't bother me since most of my attention is going to tuning the engine, feeling how the transmission shifts, getting the brakes dialed, etc.
My car rolls down the road silky smooth as well, just has a squeaky door hinge. It annoyed me at first, but I've decided that my attention would be better spent making sure it drives fine.
