That's why there's (typically? usually? always?) two maintenance schedules for cars... "normal" use and "severe" use. Severe use is stuff like driving short distances, stop & go, dusty conditions, extreme cold conditions, etc, etc. It would be really difficult to determine ( I think ) how much of a "benefit" there is to eco-driving vs normal driving from a wear & tear perspective, with so many other factors that come into play.
Take my situation for instance... there are two routes I can take when commuting to work. One is ~75% freeway, the other is 100% surface. I get worse FE on the freeway, but gut feel says it's less stress on the car being able to cruise on the freeway in a single gear than taking the surface route with the more frequent full stops and the associated gear shifts...
