I agree.
If there is 60 zone on a freeway, with cones everywhere for MONTHS on end but no work being undertaken, of course people get slack and disregard it.
The crews really do themselves a bit of a dis-service at times. Boy who cried wolf kinda deal. And often the signs are just wrong / contradictory.
There is one bit of Perth freeway for many months now where the works are 30m away and a concrete wall separates the work from the traffic. The concrete wall that was always there, so nothing has changed. It is 80 (down from 100) 24/7 and nobody slows anymore. It would be amazing if you saw a worker there (I never have)
Bloody stupid.
But I can see the converse like Tonz point of view. If you had almost been cleaned up so many times you would get sick of it.
Maybe the safety mob needs to do a national standard matrix to assess what works need what restrictions - cos it is clear you don't need some of the ones we see. Less restrictions - and then more enforcement of the ones they do have
