Do they? Because quite simply it doesn't seem like the evidence backs that up - let alone the brutally obvious fact that if you stand next to a speed camera you'll notice all the cars just slow down for the camera. If what you meant to say was 'Speed Cameras make the 30m of road that they're focused on mildly safer than it was before whilst mildly increasing the likelihood of accidents due to unexpected braking in the local area at the cost of introducing a regressive tax' I would totally agree.

There's a rise in speed cameras that record average speed over a longer span of road - on the A2 highway here it's very effective, a twelve lane highway where nobody goes above 100 km/h.

The trick here is to use a pair of speed cameras for measuring average speed over a stretch of road. Everybody and their dog knows just where the three local speed cameras are, and drive accordingly (sigh). The average measurement in the subsea tunnel we drive to get off the island? Hard to beat, unless you want to go for less enlightened tactics like driving like a bat out of hell until you approach the next speed camera, then pause until you've waited long enough for your average speed to be under the posted speed limit before proceeding past it...

  Highways are exactly where a little higher speed makes the least difference in safety. I'd rather that drivers match each others' speed than have congestion enforced by cameras.

    A bit late to reply, but today the Norwegian Broadcasting Co. ran a story on how effective average speed cameras were; they are currently deployed 27 places, and overall, the number of deaths and severe injuries is halved compared to the situation prior to average cams being deployed on those same sections of road. I guess it could be argued that the increased safety of highways is taken into account when the speed limit is determined - and perhaps also that the idea that safety is excel leads people who speed to exceed the posted limit by a larger margin? Edit: also, the average speed ones perhaps unsurprisingly led more drivers to observe the limit - on average sections, 1 driver in 7000 was caught speeding; single cameras? 1 in 1680.

Because quite simply it doesn't seem like the evidence backs that up French stats show a large drop in road casualties linked to the installation of the first fixed speedcams (2002-2003) although actually, it started dropping when it was announced that fixed speedcams were going to be installed: http://s1.lprs1.fr/images/2014/01/20/3512371_ide-tues-routes-2013.jpg http://s1.lprs1.fr/images/2014/01/20/3512371_ide-tues-routes...
