There's no such thing as luck when one breaks on a Honda, either, but
people accept timing belt changes as a maintenance item.  You're going to
see more and more gas engines going to interference designs anyway, due to
emissions requirements.

Keep in mind that most timing belts have a *time* restriction as well as a
milage restriction.  Rubber decays with age, so you can't replace them
strictly by milage.

I'd say that once they're done with the motorcycles, the boomer cars, and
the pickups running straight pipes, then people *might* get interested in
quieting down diesels.
