You're right, Daox. An example being longer-lasting brakes.

My take on the point at the top:

Tires: Some cars will wear the tires unevenly if they are inflated to the specified pressure. Inflating them higher can cause longer and more even wear. I've seen this firsthand with my Civic and Odyssey. At the door placard pressure, the tires wore out on the shoulders. At 5 psi above, the tires still wore down on the shoulders. At sidewall max, the wear was even across the tread. In both my examples, higher inflation pressure extended tire life.

Throwout bearing: You should never ride the clutch. That's bad technique, not a hypermiling issue. You should shift into neutral, only using the clutch for transitions.

Automatic transmissions: Read the manual and make an informed decision. Don't be stupid.

EOC: My synchros are fine at 175,000 miles. Basjoos is running his original clutch and transmission at 500,000 miles. It may be an issue in some cases, but in others it is not.
