This DOES kill people. I remember driving in OZ in 1971 (after I had been
there for several months) somewhere in the middle of Queensland wondering why
the approaching car was on MY side of the road - I was in the wrong. You have
to keep your mind on driving on the LH side of the road if you car coming from
North America.

It's the narrow outback roads that'll get you. With line markings and
divided roads on the major (and minor) highways, you should be able to
keep on the correct side of the road. But when it shrinks to a single
lane of bitumen and passing cars have to put a wheel onto the shoulder,
or it's totally unpaved, well, it gets a bit more problematic. The
sudden appearance of an oncoming car at a bend or crest and the foreign
driver reflexively pulls to the right-hand side of the road, at the same
time as the oncoming driver reflexively pulls to the same side.

There's another place where oncoming traffic can be a little tricky, and
that's on Fraser Island, where the long ocean beach is an officially
gazetted road. In general, traffic keeps to the left, but sometimes,
depending on the waves and the firmness of the sand, cars will pass each
other on left side to left side. The protocol is to indicate which way
you are going with your blinkers and there is usually no problem because
visibility is excellent and you can see oncoming traffic for kilometres
in advance.

Pete, noting that it's that 0.001 percent of the time that will get you.
