120 km/hr?

NewstalkZB reports:

New and existing “roads of national significance” would have a 110km/h speed limit if they had been built to a high safety standard. 

Brown said the Government was seeking feedback from the public on potential 120km/h speed limits on “roads of national significance” able to safely accommodate that speed. 

If the engineering is done well, then I see no problem with 120 km/hr limit on very safe roads. It is a limit, not a target.
