Great post, Doohickie. You, my friend, get it.

Vehicular Cycling: Operating a human-powered vehicle on the same roads, with the same rights, and in accordance with the same rules as all other vehicle operators.

There's nothing in that definition that requires a vehicular cyclist to be uncooperative; to hog more road than is needed for safety; to be "dogmatically addled"; to have an opinion one way or another about "bicycle infrastructure", as long as it does not interfere with the same roads/same rights/same rules principle; or in general to be an arrogant and selfish sob to other road users.

What you have described is vehicular cycling at its best.
