Bruce Highway aka world's longest carpark

The digital speed signs on the Bruce highway have to be the worst implementation that has ever been introduced.

There has been countless times where they have reduced speed to 60 for no reason other than the amount of cars on the road, eliminating the purpose of a HIGHWAY. No roadworks, accidents, nothing, just slowing everyone down for no reason. And then you get the monkeys who slam on the brakes upon approaching the speed sign, only to then speed back up to 100 before slamming them on again when reaching the next.

You cannot convince me that they are a good idea. If people can see the flashing of a speed sign, they can see the flashing lights of a tow truck or emergency service if there is indeed an accident and slow down then. But nah let's just slow everyone who is in a 40km squared radius just because, increasing the risk of another accident.
