Wrong...all you get is a day off work alright...but you get "we're right, you're wrong, pay the fine...plus costs".
Speeding tickets are just about the only area of the law where you are absolutely positively guilty until you can somehow prove yourself innocent. Even a murderer with firm DNA evidence against him and a bloody knife in his hand standing over a body has more of a presumption of innocence when compared to Average Joe Motorist who's been caught going 10kph over the limit on an empty road...
