pedestrians have the right of way

hah, not in London they don't. Drivers, especially the cabs and buses, are ferocious there. Their philosophy is more like "I'll go ahead and hit him. It'll teach him a lesson." My friend who's been studying at the Notre Dame branch campus in London since January said that one of the guys in his program has already been injured by a car hitting him. While I was there someone got killed by a bus. But I guess it's probably this way for any huge city.

And speaking of traffic, have there been any infrastructural studies done that conclude whether traffic circles or 4 way stops are better? I'm well aware of the occasional annoyance of 4 way stops, but it seems like roundabouts are such an indirect path.
