Another cultural observation, when living in Boston, my partner and I both found it strange that if you were standing on the side of the road, cars will stop and wait for you to cross, even if you were nowhere near a crossing or intersection. Cars seems to give way to pedestrians anywhere an everywhere.

In Australia, cars wont stop for you unless you are at a crossing, and even then you need to make sure they have seen you. Cars zooming through a green light are not going to be looking for pedestrians walking against a red walk signal. The onus is on the pedestrian to not be hit, not the car to avoid the pedestrian.

Update: Also.. its hard not to take this persons criticism personally, so when they say "the UK / Australia model where everyone obeys some stupid rule written on the wall over their own intelligence" I would just like to respond that is a combination of wanting to be polite and courteous to the sign poster, and intelligent enough to know we don't know everything, that the sign might be for our own safety. :)
