Do you have kids Dan? I have, and even they can use a ped crossing safely without knowing the legal rules, loopholes, clauses and minutiae behind its existence and use. They have been taught to stand at the crossing, a safe distance from the traffic, where they can see and be seen. Once they can see the road is clear or that the approaching traffic has stopped (and not before!), they can then proceed to cross the road, still watching in both directions for any other approaching vehicles.
It's child's play really, any idiot can do it (or not as the case may be).
And your point is? Just because we have to teach our children that car drivers are dangerous and don't follow the rules, doesn't mean car drivers have an excuse for being dangerous and not following the rules.
