I dont see how this addresses the "glued to the speedo" phenomenon you claim will happen, the abusers of the leeway would have had their eyes 'glued to the speedo" so they could travel right on the edge of that leeway.
Let's see how simple I can make this.
Some drivers are happy to drive within a small margin OVER the limit, because they know they will be extended that leniency. They check their speedo's
occasionally to see that they are within that leeway.
Once you take that leniency away and allow no margin, they feel the need to check the speedo more often because they know that the slightest increase in their speed above the limit, places them at risk of being booked.
OK?
And I should add, this obviously doesn't apply to every driver - it relates more to the incompetent/unsure/timid and elderly drivers. Admittedly, some within that group never drive AT the limit in the first place so it wouldn't trouble them. And I did mention earlier in this thread that,as this is an RTA proposal, and, God willing, our beguiled Labor Government in NSW dies at midnight tonight, it won't get up. The Labor mob would have gladly pounced on it as another source of revenue (hell, the RTA also has a document proposing increasing the number of mobile camera sites in NSW from 114 to over 3,000) but O'Farrell has stated that he doesn't agree with the concept of privately run mobile cameras, and also that he believes speed limits should be raised on certain roads, so I believe the No Leeway proposal won't get up.
