  This is an example of "normalization of excellence". A modern car has several thousand moving parts, high temperatures, high pressures, an oxidizing environment, and is subjected to potholes and wide temperature swings. That it is expected to survive 200K miles is a miracle. Before the model T, a car that would last 20K miles was a considered a reliable car. The model T pushed those expectations up to 50K. Post-war expectations increased to 100K and the Japanese pushed expectations this millenia to 200K. At the same time that lifetimes went up, maintenance went down. You used to have to regularly inspect tune and replace stuff like timing chains, spark plugs and seals. A couple of comparisons: a computer fan has an expected lifetime of 10 years, and it's way simpler than a car. A fighter jet needs 16 hours of maintenance for every 1 in the sky.
