It's because you're in Adelaide. If it were in Vic... you would have been breath tested, drug tested, (still awaiting results mind you... useless) you might be handcuffed... maybe. And you would be standing on the side of the road with no car (for it now has a canary for having an "intercoolant" and is being impounded), scratching your head saying, "what the f**k just happened!?!?" And just as a final kick in the balls, another cop will drive past and books you for loitering!.... count yourself lucky... you should be sweet!
