Looks like they don't speculate much on it -- they mention improvements in driver behavior over time and maintenance. Not bad, but my first thoughts were:

* a 20 year old vehicle is often driven by a person with a different socioeconomic situation than someone with a 1 year old vehicle, and those economic situations correlate heavily with other driving behaviors.

* as vehicles are getting safer and more powerful, highway speeds are rising, so 20 year old vehicle that are just keeping up with traffic are going faster than they used to.
