I find the reverse - today when I was waiting to cross the road the lights changed as an ambulance came towards the pedestrian crossing lights flashing and siren sounding.

I stayed on the pavement, but this idiot walked across the road - OK - quite safely, there must have been all of two seconds to spare before the ambulance passed.

I surprised myself by experiencing a split second of wanting to go over there and saying something - and then a whole half second of knowing what it was to want a double handed sword and the freedom to use it.

Of course by the time I got across the road he was long gone and the red mist had dispersed...
