Well, at least you learned that you cannot assume such a thing. Double bonus in that it did not cost you your spleen, or even your life. I also noted you mentioned having your left foot on the curb when you waited for the light change. Really? Is this in the UK? No, never mind, you say the cager turned right (right?) in front of you. We call this a (potential) right hook. Most of us would be good with not being hit. What do you hope to accomplish sending useless (rear view) documentation of a non-event?
