Worst drivers I have seen in my time in 20+ countries and 4 continents are WA drivers. They are not bad dangerous but bad annoying and incompetent.
They love to drive 10 kmh under the speed limit.
They love to come out from a side street or their driveway, cutting you off, then driving at 10 kmh under the speed limit.
Oddly, if you are behind them, when they have to stop at a stop sign, they will wait to give way to cars that are >500m away. They can only take one shot of adrenaline for the day.
They come to a roundabout and … stop.
They frankly admit they don’t know how to merge on freeways.
They turn left from the right hand lane, slowing to a near stop despite all the traffic on the highway behind them. Because they learnt how to drive using a tractor.
And these are their better features.
I call them “precision drivers” in the same way that John Howard was called Honest John.
