I'm a grave menace to society

What is important in trauma reduction is the speed of impact, not the speed of travel prior to braking.

Speed of impact is directly related to speed prior to braking - always had, always will. (ABS MAY have made a hiccup in the graph but in a year or two it will level out again - just as it did when hydraulic brakes came into being, and boosted disc brakes etc).

Um. Yes it's related, but there are other factors involved. Like, how far away you are when you notice the hazard and start braking. Hence why I'm always more nervous of tailgaters than speeders with a clear road ahead.

(Note the difference between an explanation and a simple 'bollocks')

Thank you. Glad we agree on something

... (provided I'm on my bike, which tonight I wasn't) ...

so hang on...you were riding an 07 blade....and you bothered to stop? the speedo goes to 300 for a good reason u know....

Erm ... amazing how many people haven't picked up I wasn't on my bike.

Another strawman? When was there ever a 20kmh tolerance?

until i joined the HWP in 2000, there was a generally accepted 20k tolerance in the south waikato.

i was also scraping dead guys/girls/babies who had been driving/driven too fast, and in the absence of concentration, or someone else doing something they didn't expect in front of them, off the road, on a reasonably (like every week - sometimes every day) regular occasion.

for the first 6 months of HWP in the south waikato, excess of 160km/h tickets were common - sometimes 5 a day. speeds over 140k were common. pinging under 120k was a waste of time, when there were 135-150k tickets to write.

after 12 months the high speed numbers had dropped to a trickle. fatals in my patch dropped by, i estimate, 90%.

fatal numbers are now at an all time low. i believe though they have plateaued, and something significant now has to happen to drop it further. speed enforcement pressure will remain. driver behaviour and skill will be the next target. don't ask me how.

BTW, the 10km/h tolerance came about primarily as a directive to standardise across NZ - it took the guesswork out of joe public not knowing if auckland cops had a 30k tolerance, waikato 20, bop 10k etc. everyone's 10k. simple

[Usarka]

how much of the low fatalataties in the waikato is due to the big new road they put in rather than people adhering to speed limits?

What is important in trauma reduction is the speed of impact, not the speed of travel prior to braking. The speed of impact is governed by a lot more, namely the effectiveness of the brakes, tyre grip, suspension set up and condition, vehicle weight, reaction time, angle of impact and probably many others. Also, the trauma level at any given speed of impact will vary widely depending on the safety features in the vehicle (air bags and the like).

The police estimate of the speed prior to an accident is probably wrong most of the time anyway. In these days of ABS etc. skid marks are no longer an accurate measure (not that they ever were).

Crap!______

This is KB... Everyone reads posts carefully before responding so no-one gets the wrong idea...

Latest corones court down here included a case where one dead and two badly injured - those not so injured WERE the only ones wearing seatbelts.

Oh, yeah they weren't exceeding 100kph - but they were exceeding the recommended 65kph the sign posted prior to the corner.

NaH, SPEED NEVER KILLS - CRASHING DOES.

Quite correct! That's why I try very hard to avoid said crashing!

Now can anyone say by what factor the likelihood of crashing increases as speed increases...?

It doesn't increase at all if you're speeding to the conditions.

what new road is in the SOUTH waikato?

and i used to work in huntly while it was still the killing fields up there - i still recall personally attending to 19 deaths due to car crashes in october 1991. a big call for a 23 year old kid back then

Yupp .... it increases by LOTS , but im sure we all know that.

[bryce]

it may be because you were on a bike.i was on s,h, 1 ,400m behind 6 cars, came over a rise still 400m behind the last car ,the cop had past the 3rd car when i came in to his view. it turned on his lights did a u"e, i got an $80 fine 4 113km . months later i was following a white falcon over napier-taupo @ 140.desided to pass, got to the drivers window to see a cop driving and all the radar etc ,so slowly pulled away with out trouble.
