at the end of the day if most riders were doing the right thing and riding to the conditions, the accidents wouldn't occur.
And this sums it up entirely.
One of my favourite roads, from The Gap through Mt. Nebo & Mt. Glorious to Somerset, is well known as a 'danger' road. Sure, there's a bit of debris here and there (uh.. it's a forest. There are going to be leaves & sticks falling from trees), but the speed limits are quite accurate (low in a couple of places) for safe motoring.
Unfortunately then some turkey does 170 in an 80 zone, wipes himself out, and they want to reduce the speed limit further. What they don't understand is that this won't achieve anything except frustrating the riders who ARE doing the right thing - perhaps to a oint where they also disregard the speed limit "Oh well I'm fucked anyway, I may as well go for it"
These taxes aren't such a bad a idea but they need to subsidise track days, B&C courses, and the like, to get the demons off the road (and many of us are demons, even if only for a sequence of half a dozen corners before settling down again).
