Whatever the situation you’ll probably find your employer will pay the penalty rather than have it doubled whilst you try to defend yourself. I believe the offence is committed if you are stationery for more than 2 seconds. The penalty is sent to the vehicle owner. Happened to me in London, 4 years ago, the company paid the £60 penalty and took it from my wages. I rang the council for a copy of the video, they invited me to see the video of the alleged offence but I would have had to travel to their offices, they wouldn’t not send me a copy. Robbing sods the lot of 'em.
