Fast and safe?

Been saying it for ages.

The more time you spend on the road the more likely you are to have a accident.
The more you speed the less time you spend on the road.
Therefore the more you speed the less likely you are to have a accident.

Quite a good read just from the first page

A fair bit of it is years old. eg Transport minister Annette King is quoted from back in 2005. Still some interesting stats tho.

Fine in principle and on a mathmatics/stats level but probably doesn't translate to real world very well.
Now most of us here are prob 'good' riders and drivers but will have had accident or two over the years involving other road users and of course it was their fault right :)
So what matters at that point in time when the reaper arranges a meeting between two strangers???
Only your impact velocity and the condition of your vehicle and protective gear.

I'm all for a bit of speed here and there and bending the rules to ones own desires, but you just cant say faster is safer cause it aint.

BTW read that page then clicked 'about us'... two computer nerds and a sparkie.... yeah guess they know more than the experts.

Interesting read ,

I'm still riding my # 3 Hayabusa, 60k's + and I guess I'm just edging on the side of lucky

Never had a ticket but been pulled over once or twice :-)

Not really that interesting a read but as someone else posted its all been said before,probably before the latest to say it was born.Dont underestimate luck though eh tis a wonderful thing,spend a lifetime on two wheels which may result in a total lack of two wheeled riding ability or consider yourself gifted either way without luck chances are your not going to collect a pension.

Cassina!!!!! We would value your input here

Seems to be an old website, after flicking through the pages for 5 minutes, I can't see any recent updates?

So, it pretty much says the same thing that anyone with a memory of 6th Form Physics already knows - that 99% of the Government battle Cries are BS.

My personal pet hate is Speed Kill - Speed Doesn't kill, Sudden deceleration however can be very fatal

Suddenly decelerating from greater speeds increase the chances of being killed.

[Scuba_Steve]

I don't know, speed has been shown to cause death... However speeding still has not. :shifty:

Actually, no.

http://formulas.tutorvista.com/physics/deceleration-formula.html

The 2 important factors is the Denominator in both equations - expressed as either distance traveled, or time taken - the shorted the distance travelled or the shorter the amount of time the deceleration happens over - the higher the deceleration and the higher likelyhood of injury/death.

This is why you can decelerate from 140 Mph to 0 with a commercial airliner landing without issue, yet going from 50 kph to 0 in the space of half a metre is fatal.

Clearly we need to legislate to make sure that all accidents take place over sufficient time and distance to be safe.

Small Denominators in Physics Equations Kill!

I would hardly call 20 seconds of braking down a 2km runway as "sudden deceleration".

Using equal situations, with the only variable being speed, hitting a power pole at 140km/h will do more damage than hitting a power pole at 50km/h.

Just because you're speeding, doesn't mean you are going to crash slower.

I agree speed limits kill more people than they save, but not because its safer to crash at higher speeds. That's just stupid

The experts only communicate what they're paid to. Usually by a Government with a point to make. When it comes to road "safety" I'd trust two computer nerds and a sparkie ahead of any expert. Their agenda is plain and grotesquely ill-informed is usually better than deceitful. The experts are usually communicating a justification to right thinking people for extracting more money from a minority group.

[Big Dave]

The experts ... money from a minority group.

What have the Romans ever done for us?

[James Deuce]

There's that nose thing. Oh, and paved roads.

[pritch]

Sudden deceleration however can be very fatal

Interesting concept; degrees of fatal? Sort of like being a bit pregnant.

Dont forget the Aqueducts

[James Deuce]

I cant be stuffed getting into the debate all over again but I do agree that if the roads were better travelling fast would be safer.

No you don't.

[haydes55]

Regardless of road conditions, the safest speed to travel on that particular piece of tarmac, is the speed at which you are under full control and have room for fuck ups and the unexpected.

A 1km stretch of road could be safe at an average speed of 100km/h, but the same stretch could be 100% safe to reach 160km/h for half of that stretch and only 75km/h for half.

There's no way a speed limit can be set for hundreds of kilometers of road and be deemed to be safe. The safest way to travel any road is to constantly assess the road, road condition and other factors to deem appropriate speed for any circumstance. Keep road users alert and thinking about the road, rather than hitting cruise control and watching the road go under their vehicles.

Slower speeds are safer IF you crash. And if you have crashed, that means you weren't judging the road and other factors well enough. I'd rather have no road rash or panel damage than crash slow enough that I don't die.

Shut up and ride yer bike :)
