I remeber I saw one episode of fifth gear testing those laser speed gun. One of the result was that if there are reflective objects near the road, those speed gun can make up to 40% errors, said by a German expert. On freeway, that is the difference bwtween speeding and reckless driving. No one knows, and they try to stop anyone who wants to know, how they calculate the tolerance.

PS: Three month ago, on manning rd, I nearly got hit by a commordore driving on my side of the road with three police car chasing it on opposite lane, I haven't hear a word they caught the driver, USELESS!
