No one has yet explained how driver's are "robbed" or how "freedoms are lost".
I can't speak of the UK law and what freedoms they have, but if it is anything like over here...
No privacy -- even if it's just the top of your car. And "Innocent until proven guilty" goes down the toilet if you are watched until you purposely or accidently break the law; you're nothing more than a criminal in waiting, which is what they must think in order to use these, after all -- they already have cops to do this job. Cameras the same.
Again, assuming the UK is like the US:
YOU pay part of your money in taxes to use the road, including the salary of the police, which means you own part of that road; being fined for abusing something you own a piece of, is like arresting someone for breaking into their own out-right owned home.
And there's no real way to know if the system has been tampered with to pruposely get you ticketed. Over here in the US, Lockheed Martin set up cameras at lights (I think it was California) and they purposely made the yellow lights shorter so more people would end up running a red one, and getting a ticket. They got caught, thankfully.
Privacy being lost yet again (isn't it the UK that has a system of street cameras in many, many places? Creapy), and people are making excuses for it; one at a time until there will be no peels on the banana of freedom.
Also, you are being treated like a criminal in advance of a crime. A government who thinks you are a bad guy when they are not looking, and sets up a system to spy on you to catch you in the act (again, whether purposely or accidently) and then fine you ... that's one to be VERY wary of.
Of course, this is all beside the point when it comes to bad, repeat offenders: some of you just need to slow the fuck down and watch out for other drivers.
