I always sit in front of the numberplate of the lead vehicle so that this situation is prevented
That's a great piece of advice, Dave. I try and position myself to make myself as visible as possible to the vehicle behind me. For a car I find this is directly in front. For a lorry it is of course different, you have to get further ahead as the diagram illustrates. I also agree that the more "infront" of them that you are, the temptation for that car to try and race you from the lights is reduced. They are forced to sit behind you and in theory, can then pass you safely and at a safe distance further on. I will also generally pull myself in to the left a bit after starting from the middle of the road out of an ASL, but don't dive for the gutter. It's just not a safe place to be. You just have to get used to and be confident with the noise of a car sitting up your tail and move when it is safe, not when you feel forced to. Again if they are right behind they aren't tempted to try and squeeze past like if you are sitting on their front left.
Anyway. Be safe. Be seen. Be assertive.
