Ok, so no one particularly likes them, some think they are only there to generate revenue or increase detection rates by 'shooting fish in a barrel', & some of these arguments 'can' be valid. However, from personal experience, on a daily basis, I see a significant number of motorists flashing their head lights to warn on coming speeding traffic of a speed van ahead. The route I usual take is a primary road, but contains a number of stretches where there have been serious collisions, yet the warning flashing continues.
Recently two cars racing each other passed me at a frightening speed, but then got caught in traffic, luckily for them on coming traffic flashed the row of traffic and all slowed down while passing the speed van. Too many deaths and life altering injuries are caused by serial speedsters - I think it's time to have another think - to flash or not to flash - who are we really helping, or more importantly, what could we possibly help to avoid, by not flashing?
