"These directions are for planning purposes only. You may find that construction projects, traffic, or other events may cause road conditions to differ from the map results."
Similar directions are available for all the locations I tried in Australia - Alice Springs, Tasmania . . . Note that if you start your trip in Australia, the distances are measured in kilometers, but if you start in the USA they are measured in miles. I suspect, like the driving from New York to London directions that I blogged about some time ago, these too will disappear before long. At least this time they suggest that you should kayak across the ocean rather than swim!
