I agree. I can’t say that I love speed cameras, but these do genuinely have a big impact. The other thing they tend to do is even out the traffic - everyone is travelling at a speed close to the vehicles around them. (It’s rare for vehicles to drive a lot slower than the camera-enforced speed - whereas there is a lot of speed variation between vehicles on motorway stretches without cameras.) So in addition to the reduction in speed, you’ve got smaller speed differences between vehicles and also a much more even and steady traffic flow which can help prevent that traffic jam inducing stop/start behaviour. I reluctantly think they should be used more widely. (And I say that as a U.K. driver who is not unfamiliar with receiving the odd speeding ticket in the past).
