It's not a serious question at all because you know the answer. People only laugh at what in their opinion is stupidity and watching someone ride up the center of a lane would be as boring as watching paint dry. If you think I am callous just say so. Don't try to construct an argument based on your opinions because your opinions are of value only to those that hold similar ones. In my opinion anyone who wants to hog a vehicular lane on a bicycle is arrogant and stupid and when they get creamed it's hilarious.
