You've lightly touched on a subject that has been confusing the daylights out of me for years....
When watching cable TV here (called Foxtel here) my preferred shows are the automotive ones, and at the end of a restoration there are always the shop owner driving the new (but unregistered) car on the road to test it. What are your regulations surrounding that? I understand every state there is probably different.
Then there's the Outlaw Drag show where full drag cars are racing on the streets, at night. What's the go with that? Wiki seems to indicate it's done with state permits, but the show puts a big emphasis on how illegal it is.
Over here if you even try to take an unregistered (therefore uninsured) car on the road you would get the book thrown at you..... The Compulsary Third Party insurance is a component of the registration fee here, so no registration, no CTP, therefore the public aren't protected in the event of an incident.
