This one time I go stopped at a fruit fly control point on the border between South Australia and Victoria, near Bordertown.

The person staffing the control point indicated with hand signals for me to stop on the highway in the lane I was in.

So I slowed down to walking speed and pulled off the highway into the car park next to the office.

The agent then lectured me about not following instructions and that she could fine me for disobeying.

I then calmly explained to the agent the reason I didn't stop in the lane on the highway: drivers of cars and heavy vehicles are known to have a terrible habit of not seeing other vehicles stopped on the road.
