As a pedestrian, I don't want cyclists turning left on red. Any cyclist that comes near me when I'm crossing the road on a green man is risking a sore nose.
This isn't so much of an issue in the States as there are relatively fewer pedestrians and cyclists compared to car users. I've known people drive 50 yards to visit their next door neighbour, and I've stayed in a few out of town hotels were there was simply no pedestrian route to the shops 400-500 yards away. When we asked reception how we get there, they said they would arrange the hotel courtesy bus. They were really confused when we said we wanted to walk.
When it comes to transport, the USA is not a good model to follow, imho.
