Left Hand drive for Australia?

[Terror_Tree]

Just a thought, now we don't make our own, how many more vehicles would we have access to if we were able to drive LHD on Australian rods? Yes I know that there would be safety issues.

My Father told me that during WW2 there was a proposal to make Australians drive on the left as there were so many US military vehicles on our roads. Would have been a good time to change, as there weren't a lot of cars on the road then.

Could it be a possibility for the future? Interested to hear peoples thoughts.
