I should also note that I was hit by a car once in a RTOR on red situation. I was in the crosswalk on a bike, with the permissive pedestrian signal. The driver, at the red, was looking to her left to see for an opening to make her RTOR, but never bothered to look ahead to see for pedestrians with the right-of-way (i.e. myself).
I wasn't hurt, although my bike was a little damaged. It was really eye-opening, because I think she meant well and was a fairly responsible driver. What it taught me is that in busier urban intersections with pedestrians, it's very hard to process all of the information to make a safe RTOR.
My own policy preference is no RTOR during daytime/working hours, such as 7 AM - 7 PM.
