Gas isn't $6 a gallon here, I just filled up yesterday for $4.55/gal in the metro area.
Being able to read, drink, or sleep during the ride doesn't counteract the fact that it's slow as that's still a couple hours more that you'll be spending on the transportation portion of the trip rather than at your desired destination.
Even if you do use it frequently, I don't see how you couldn't want the ride to be faster or offer literally any empirical advantage over driving. The benefit of reduced stress that you listed could be accomplished by having someone else drive you there too and it would be faster and even cheaper.
Advocating/settling for complete mediocrity in public transit is exactly why it sucks here.
