Tried that for a while.
Now in an effort to be more inclusive, kid friendly, and PC, I stick as much of my body out the side, make eye contact, and continue to wave like a fool till I pass them or they wave back. Half the time you get crazy looks, but the half the time that you get a sheepish wave in return is worth it. Either way I refuse to be ignored.
