Actually I hold the opposite view. These things do not have any impact on people who respect the rules. The rules are generally there to ensure safety of others or fair use of resource. If you get a ticket from a speed camera or a parking ticket or similar it is because YOU failed to respect the regulations put in place to protect others rights and indeed lives.Yes in hindsight i should have argued with it more but at the time i was bogged down with other things and i kept forgetting i had the fine even. Oh well live and learn. The PCN guys are scum IMO, money making racket and nothing else.
Its along the same line as police camera vans. Privately contracted companies (not the police) out to make a quick buck only. They do not offer anything in terms of keeping speed down and they are often on high speed roads in concealed spots.
Close to 2000 people die every year in the UK due to traffic ‘accidents’. 30% of these list speed as the contributing factor.
