peckhambog, you ask "how many tragedies" etc. Regrettably, it is a fact,in certain parts of the country,that one of the criteria for a speed camera (or other traffic calming measures) installation is that a death MUST occur before one will be installed. I do not know if this applies in Southwark, perhaps JB can answer this. I feel that speeding will not be reduced in built up town and city 30mph zones until we introduce a radical, and yes some would say draconian,change in the law. I feel we need a system whereby speeding in this instance is treated as follows: 1st offence: Relatively Substantial Fine eg: ?100. This is on the basis that anybody could "drift" over the limit by accident in a moment of loss of concentration, which, although I know is unacceptable, it does happen. 2nd offence: Short Duration Driving Ban eg: 3/6 months. Having had the benefit of the doubt as above, no excuses/reasons as the driver should have been wholly aware of their circumstances. Further, the ability for the courts to go straight to sanction two for a first offence if the speeding was substantial eg:anything over 40mph on the basis of at those speeds you would have been aware of going to fast. Also, the normal licence endorsement of three points at a stage one and two, thus accruing six points toward any other possible driving ban. Thoughts on this would be interesting.
