I think the dangerous situation this is trying to fix is when drivers turning right fail to see you stopped there, ready to go straight. Drivers are usually looking left or ahead when turning right, and often fail to look right. I’ve been hit this way myself. Being able to legally go straight on those reds would help a lot.

The alternative, which does help, is to wait in line behind a car, but often drivers dislike this more (have been shouted at for this as well).
