With a jaw/noggin my size I can fog up a pinlock at less than 30.
Political Correctness, the chief weapon of whiney arse bastards
Or just older, less active.
Reasons I have given: we are doing lots of slow riding and the only other realistic option is shedding gear. Eg doing walking pace exercises for over an hour. Around bike festivals.
Reasons I have been given?
I like to smoke while riding - Explains the burns in the beard.
I like to eat - from someone with burn scars down one cheek and the chin. Always blow on the pie. Especially cheese pies.
I like the wind in my hair - always from bald men.
So the girls can see me smile - always Middle Aged, usually overweight, bald men with dodgy teeth.
Stupid phone / Tapatalk, apologies in advance.
Research was done in UK on police drivers and riders into accident rates and so on (sorry no links, so choose to disbelieve if you like). The result was that the accident rate for bikes per km was lower than for cars but the effects of those accidents was higher on bikes. The net result was they considered that for police trained and assessed drivers/riders the risk was the same.
BTW I didn't think this was the ACC thread so I fixed your quote
Legalise anarchy
BULLSHIT.
The speed advisory figure is measured by driving a vehicle around the curve at a constant speed and measuring the lateral forces acting on the vehicle using a side thrust gauge. Two runs that yield the same result must be made for a sign to be adopted.
The speed set for the curve is 15kph less than the 85th percentile curve approach speed for speed of 30-60kph, i.e. the speed at which the top 15% of traffic would approach the curve, i.e. the speed just before the traffic begins to slow down. Therefore if the sign says 15kph then the 85% percentile is travelling at 30kph. For speeds of 80-90kph the advisory speed is 25kph less. For 110-130kph the advisory speed is 35kph less. These speed guidelines were set in the 1990s and are now out-of-date because overall speeds are lower and vehicle capabilities are higher. Although this doesn't stop surprisingly frequent rollovers of heavy vehicles each year through misjudging the corner.
Signs are placed at least 120m ahead of the curve in rural areas and 60m ahead of the curve in urban areas.

Have you ever noticed those little black tubes running across the road? they are surveying speed and volume of traffic at a certain point.
and yes, some councils pay for serveyors to sit and watch. Auckland watches traffic flows on cameras.
This is the important bit ... is how the advisory speed is calculated for a corner.
