I personally consider that lifetime on a Toyota product is around 500k miles. As for your theory would probably be great if the car ran 30mph constantly, but the stop and go creates gear lash etc. It also depends on the specs on the equipment, as some is specked to fail earlier (cheaper) and other products can run for a very long time do to the specs on the metals, tolerances, etc. Cars do not live in an ideal environment, and consequently will have failure do to outside environments. Pot holes, rough roads, dirty conditions, slow and stop and go situations (commutes) all contribute to wear and tear. I can guarantee cars are generally not made to last forever, yes they are better than yesteryear, but still have issues with these conditions. I know of some old Mercedes engines that have gone 500k to 1 million miles with very few failures, but those generally were diesels.
I totally agree here on your comments. Lifetime warranty is a very broad statement. Just use some common sense on what you
are considering on parts replacement. Everything wears out at some point, or at least gets out of tolarence.
