It sounds good providing video evidence is there to back up the claim, which shouldn't be a problem in tailgating or middle lane hogging.
I think part of the problem is that people get no tuition at all on how to drive on motorways, so often people are not aware of the need to pull over when not overtaking. There should be a compulsory Motorway guidance session after you pass your test. Doesn't apply to tailgaters though, they are just idiots!
