We have shitloads of speed cameras, marked and unmarked police cars with speed cameras fitted. None of this namby pamby pretend speed camera nonsense they do here. Undertaking is commonplace though: https://practicalmotoring.com.au/voices/the-australian-overtake/

Ah. human nature then: "You wont' let me overtake? I'll undertake.
THAT'LL TEACH YOU PHYSICS!!!
Reading that article it seems having such "one off" speed checks really isn't helping.
The Netherlands has many "average speed" lanes. So, if you overtake somebody at 130, and the average speed is 120, you have to drop back a little. But you won't get a fine. And yes, there are apps to track your average.
In town of course the speed cameras do work with a "one off" system, cos there's no reason to overtake at 40 in a 20 zone.

How does that work on Oz motorways?
In Belfast you can forget about overtaking a car in the slow lane doing 65 at 70mph. As everybody else is going to be doing 80, at least... but perhaps that attitude doesn't exist if the speeding laws are strictly enforced.
Aside from some speedtraps it's a bit of a free-for-all here.
