Part of the reason I commute. Riding is riding to me. I could be 'saving' the bike/tires for when I get to do a pleasure ride, but it would be hard to justify owning a bike if that was the case. I bought it to use it, and if have burn through a set of Anakee III's on the highway, well worth the price.
The thing is, on the bike, I might take a detour to find 10 minutes of fun on a 60 minute commute. I won't in the F150. Like parenting, you can't schedule quality time, you get that in little slivers of quantity time. OTOH, I have this weekend free, and I can't decide where to go, and for how long. Option paralysis. Default setting is the west side of the state. Where is my camping gear?
