Kate,
How do they drive in Ballarat

The closest 2 I can think of :
"one hand on the wheel and the other waving to people they know in the street"

and
"one hand on the wheel and the other waving pedestrians across the road who have chosen not to cross at the traffic lights".

Kate

Thanks for replying
Ballarat seems to be a paradise full of kind people , prefer not telling you what we would do with our hands when pedestrians don't cross at the traffic lights not one on the wheel
