You will not get anythin through the door if your driving in the oposite direction.

i used to work as a take away driver and there was a gatso right beside it and it used to flash me in oposite direction at least 10 times a night, 3 nights a week for 4 years and i never once recieved a ticket.

i wouldnt even give it a seconds thought mate, you wont recieve anything
