Steve, in Eliza's case the tailgater had plenty of opportunity to pass (those Norfolk roads are long and straight in a lot of places) but chose not to do that. In those circumstances, and being a lone female in the car and with no mobile phone signal, I would not on any account stop to let it past as that could be exactly what the tailgater wanted her to do. Maybe, as females, we think more defensively than do most men, but there is always the thought that we could be vulnerable to attack in such a circumstance

I think Eliza did exactly the right thing in the circumstances.
