I read this first, but it still doesnt make sense

I can understand it for cars, but for bikes we don't have a front numberplate and the cameras seem front facing. The ones facing the other way are for the other carriageway?
The way the article makes it sound, is that bikes arn't affected by them. But if something sounds too good to be true then it probably is...
