Preaching to the choir here but if any of you (and friends and family) get the chance to watch "The woman who stops traffic" do so. It's an excellent insight into just how much of a death grip the average motorist has on their steering wheel.
If you haven't seen it already it's a about a conflict resolution/management consultant who is asked to try and un-jam three completely grid locked towns. Very interesting and a little frustrating to watch (Lots of "I'd drive less if there was less traffic" comments ).

edit: doh! "the woman who stops traffic"is the real title
