I don't think obsessive is the right word. We don't think of automobile commuters as obsessive simply becasue they always drive their cars.
In fact, I'm no more committed to my preferred mode of transportation than the typical car owner.
You've captured quite eloquently what I've wanted to put in word with several friends and co-workers.
