I have been on both ends of this situation, hitting a car behind me while trying evade a car backing into me and I have been backed into while stationary at a light and not having time to respond. In the end it's best not to try to back into traffic regardless. You just can't depend on traffic behind you to back up, especially if it is human driven, why would we expect an automated car to? It's not the responsibility of vehicles behind that car in the intersection to fix things, human or otherwise. You could also argue that a self driving car wouldn't be going as fast behind a car chasing a yellow light and could allow more room to handle this situation before it gets to that point.
