Whew. While I don't want too sound paranoid about this, it's pretty much impossible to live in a municipality that wouldn't look askance at this sort of thing. I seriously doubt most cops would bother to 'pull you over' for this under ordinary circumstances, but if anything happens that does involve the police, you get to look bad for free, not to mention opening yourself up to all sorts of legal liability.
On a more helpful note, those hard plastic, adjustable length tube carriers might be useful on a bike.
