The slow down, speed up, slow down method is plain daft.
I'm not quite sure what this method is that SafeSpeed are recomending, but it sounds very similar to a technique I use occasionally to discourage tailgators. I first came up with it about ten years ago and I've used it literally only three or four times since then. I make a conscious effort not to hold up people behind me so it's not something that I would expect to use at all often, but occasionally there's somebody you can't get rid of who's dangerously close. Under those circumstances it's a highly effective and non-confrontational way to pursuade somebody behind you to back off. It doesn't take a huge amount of attention, and it's so subtle that I suspect that nobody around me realizes that I'm doing it including the victim.
The technique is to slow down fractionally and let the gap behind me close to the point that the tailgator responds and slows down. Having matched speeds they slow down even more to drop back to a distance they're comfortable with (which is a lot closer than *I'm* comfortable with). While they're dropping back, I accelerate forwards and resume my previous cruising speed. This means that they drop back further than they intended so they accelerate to close the gap again. As they do that, I decelerate fractionally so they overshoot again, and have to react even more. By keeping my own speed adjustments out of phase with theirs I encourage them to overshoot more and more, and with just a few mph variations in my own speed carefully timed, I can make them work very hard indeed to stay that close. There's no overt aggression, no lights, braking (implied or actual) or signal that you're trying to tell them off. The closer they are the more effective it is, and so far I've never needed to do this more than two or three times before they drop back to a more comfortable distance.
I think of it as shrugging off somebody who is too close behind you in a crowd. Nothing personal, but just give me some space.
