Here is an interesting PSA, with subliminal bike advocacy. It says it for TV, but I haven't seen it yet.

This one is not at all about bicycle/traffic safety, but about traffic congestion due to lots of contruction going on in town right now (installing light rail)

(obviously this, drivers ed, isn't the thread for it, but it is a PSA and a curious one too)
