The speed restrictions are only partly there for the safety of the road crew. Sure, that is a very important factor.
But they are also there to help repair the road. If there is no seal hen the speed restrictions keep down the damage on the surface. Any breaking, any gear change, and sharp turns, puts pressure on the loose surface and can damage it. Once there is a small amount of damage that quickly builds up, so a small rut is slightly bigger each time a vehicle passes over it - even at the required speed - but worse if it is a faster speed.
So a road crew can spend quite a bit of a day repairing the damage caused over night by speeding vehicles - and do that night after night.
There is a very rough section of road between Whakatane and Ohope. It's on a corner going down hill - bumpy as. No-one followed the speed limit, so the bumps are the result of cars putting too much pressure on the area of the road works, as the tyres pushed across the broken surface.
Now everyone complains about the rough road - not realising it is largely a result of their own actions, because "there was no road crew there at the time so there was no safety issue - so I didn't follow the speed limit."
"So if you meet me, have some sympathy, have some courtesy, have some taste ..."
