In stop-start traffic all sorts of speed cameras are mostly irrelevant.

What I meant with that previous comment was not bumper-to-bumper traffic, but "regularly stopped by traffic lights" driving. Where some people absolutely will speed if they think they can get away with it, so maximising the fear of getting caught is a great way to reduce speeding.

    In that case, average speed cameras still work, and they still work better than single-spot speed cameras.

    But an average speed camera doesn't really work if they only get a few hundred metres, maybe a couple of kilometres at best, before they have to stop, and if during those couple of kilometres there's a mixture of times when they're speeding and times when they have to slow down because of other cars who aren't speeding.

    They really can only work on motorways, with many kilometres between cameras and on- and off-ramps.
