I can offer some good discount on some various surgical aids Russ. Whether or not they would do your neck any good is open to question, but it might be worth a try, just to get that 'crick' out.
Really, if it's a black spot, the council should put up a barrier, or failing that you could try dressing a little Barbie doll up as an angel and pinning it to the pole (not in a cruciform pose, for chrissakes!) with some pansies. That normally slows the traffic down.
