Lots of places also have variable limit signs that get updated based on traffic, accidents etc.

Here in NZ those seem to all be marked on the speed limit maps as 100km/h even if in some places the signs never go above 80.

Ngauranga Gorge is one such location and I believe has the country’s highest grossing speed camera.

This is why it’s important to operate with enough available reserves (fast and slow) to cover the unexpected loss of your biggest generator, transformer, and/or transmission line.

Their black start procedures are going to be getting a good workout; I hope they’re well tested.
