Just a quick update on the British road-crossing scenario: vehicles are required by law to give way to pedestrians wanting to cross the road at a zebra crossing. The only time they don't have to stop is if it would be unsafe for them to do so. However in London and the other major cities, where traffic density is very high and the law of the road becomes survival of the fittest this rule is not adhered to as strictly as it ought to be.

And to reply to McSey, in Britain we drive on the right side of the road, which is of course the left side :-)
