A law that is perceived to be unfair or wrong in any way drags the whole law into disrepute. So I don't believe it is wrong to challenge a law, wrong to break it, Yes, but all laws need to be justified so we respect them. 20 mph outside schools makes sense. 20 mph to protect the bridge may make sense, but how about information for drivers showing why a speed limit is justified would help the law gain respect. At the moment a lot of money is being raised from this limit on Tower Bridge so clearly not enough motorists either realise it's there of don't feel like it is justified.
I personally don't think that Tower Bridge is suitable for a major ring road. Where would the traffic go? The Dartford crossing is part of an established ring road. Or London or Blackfriars bridges which are several lanes wide would be more appropriate. Tower Bridge was selected as there was no alternative in the mad plan that Ken introduced which is in no way connected with "congestion" relief but as a political anti-car/van/trade vehicle plan of the interest groups he represents. He has already realised his original plan was wrong and doubled the size of the zone, it will only be a matter of time before the zone is increased further and it will be seen to be what it really is, a tax. That is why the US embassy is refusing to pay the CC charge as Embassies are exempt from local taxes.
Yes, westofbank, if their average speed goes over 20mph - there isn't a GATSO-type speed camera with lines painted onto the road, you go past a camera on an overhead gantry as you enter and exit the bridge and it measures your average speed over the distance inbetween.
Don't the new style speed cameras have cameras that face towards and behind the traffic ? I could be wrong though
I have seen roads that have the sort of "old style" cameras but they take a picture of the front of the car , so they not only get the number plate but also a clear shot of who was driving at the time, to avoid court cases like the the limos driven by chief execs of football teams and large companies where the car is registered to the company and not the driver.( the companies etc "accidently" forget who was driving the car at the time , when the recieve the NIP......)
On a lighter note and poetic justice one motorbike rider thought he would be clever when coming up to the new cameras and did a wheelie to avoid them seeing his number plate.......only problem was , that there was an off duty police officer in the car behind him at the time ..whoops !!!
Also didn't around 7,000 drivers get there points deducted and there fines returned for the lower thames street cameras a year or so ago ? after one motorist who was a bit of a legal expert and knew the ins and outs of road traffic law / speed cameras / signage pointed out to the DVLA and City police that the main sign highlighting the 20 mph speed limit was partially obstructed by a lamp post !! ( if i remember rightly the highway code states that the speed limit on an urban road with streetlights is 30 mph unless otherwise stated)
