This is probably the biggest one. Lots of pedestrians and get hit by people turning right who can't see them until the last second because of other things on the street corner (like people waiting to cross in the other direction).
There are a few intersections in my city that are notorious for this; I have an extremely loud airhorn on my bike that I use to blast drivers who allow their vehicle to move forward without looking where it's going.
I no longer believe RTOR can be performed safely by the majority of drivers— it should be banned.
Having recently been teaching someone to drive, I have strongly encouraged them to not engage in right turns unless it is clearly safe and there is no on coming traffic. Better to wait a minute than to risk hitting someone. The problem is there parents feel differently, as do the drivers waiting behind us. If people were more patient drivers, less pedestrians (and drivers) would die.
My point though is that people do just fine without it.
I would like to be able wait for the light to change without feeling like I'm being an asshole to other drivers behind me.
All major pedestrian intersections should be "all walks," where a period of time is established where no cars may enter the intersection.
If you're turning right onto a road from a private residence, then you're probably only looking in the direction traffic is coming from. Someone biking the wrong way could easily be hit.
