It is all relative to where you live and how you ride.
I totally hate tire threads becuase of comments like yours.
Other riders think that it is OK to get 8K miles from a set of tires... Sure if you never break 55mph that would be acceptable.
Some of us actually use the C-14 and occasionally exceed the speed limit. Life is too short to own a C-14 and not use its powerplant.
Others of us NEVER get on an interstate nor do we have four lane roads readily available for our access from point A to get to point B...
I personally live in the mountains and rarely see a straight road.
This gobbles up my tires from edge to edge in under 3K miles.
I am lucky to get close to 3K on all of my bikes.
I know people who are lucky to get 1000 miles on a set of tires riding only on the streets.
So before making comments on a tire thread, you need to understand, location, rider skill, road conditions, etc... We are not all the same.
Not all of us are stuck in a crappy location with crappy straight roads and speed limits.
