There's a pretty simple reason that TPTB concentrate on velocity in attempting to reduce the casualty rate on the road, and I fear that a lot of people have such a negative understanding of it due to the simplicity of the campaign.
You see, there's two different types of people in this world:
- those that are too hick to understand anything that has anything to do with math; and
- those that turn off because they dislike being treated like idiots.
I'd put myself in the latter category.
And since most of the people here are also in the latter category, I'll talk about how it's been explained to me. Any type 1s can just move on here as there will be some maths.
You see, it's all about overall reduction of speed causing overall reduction of harm.
If look at any type of crash, anything that carries mass is going to have a significant amount of kinetic energy. And as we know the formula for kinetic energy tells us that the kinetic energy is half the mass times the velocity squared, or
K.E = m/2 * v^2
So how does that work in principle?
well, if we consider for argument's sake that a rider in leathers, kitted up weighs 100kg, and the bike weighs 200kg, and the bike and rider is doing 100kms/hour, then the kinetic energy is 300,000 joules. A rider that weighs 110kgs on that bike will have a kinetic energy of 310,000 joules.
But, if we increase the speed by 10km/hour, then the original 100kg rider will have a kinetic energy of 363,000 joules. So an increase of 10km/hr has an increase of 21% in kinetic energy. But an increase of 10% in weight has an increase of only 9% in kinetic energy.
And what's kinetic energy? Well its the force that gonna fuck you up in you hit something. It breaks bones, it tears tendons, and it wrecks bodies.
But there's a lot of thick people out there. And we know that a small increase in speed causes a disproportionate increase in the energy expressed in a crash. But that means nothing to thick people, so they've dumbed it down - The Higher the Speed, The Bigger The Damage. It's true, but not many understand why it is.
I really didn't give a fuck about the message. I'd been riding 38 years, and riding litre bikes for about 14 years straight, without a major accident.
Until the evening of September 11, 2017, when a blind idiot in a Nissan Navara Ute pulled directly into my path on SH58 (Plimmerton-Haywards-Hutt Highway) from a side track hidden by overgrown bushes, saw me, and froze. Directly into the path of me and my Aprilia RSV. And I was at the speed limit (I think - I wasn't looking a the speedo so I guess it was about that speed. It was the normal speed I do there, which is about 95-99).
I can remember hearing the voices of my riding instructor in our emergency braking practice yelling at me to "brake harder, harder, you can brake harder than that Simon!" And believe, me I scrubbed off as much speed as I could.
But it wasn't enough. They estimate I hit the ute at approximately 65km/hr, was propelled four metres up and six metres forward, somersaulted twice, and landed in a heap, unconscious. I've gotten this information from witnesses subsequent to the accident. I woke up in the ambulance, spent three weeks in the hospital, and I'm still on ACC now. Broken bones and a brachial plexus injury that has my right arm partially paralysed.
The Police officer, the ambulance officer, my surgeons, my OTs, my nurses and countless other people I've talked to have told me how lucky I am - how most people don't survive these accidents.
Apparently had I been doing as little as 10kms over the speed limit when the accident occurred, I would not have survived. 5kms over the limit I would have permanently lost the use of my arm, and had significantly more broken bones.
So, I've spent the last eight weeks thinking about speed in terms of kinetic energy. And as a result, I've come to understand where these guys are coming from. Because I've had it explained to me. And there's some problems with a differing rate of velocity to what the majority of other vehicles are doing. As most other road users are travelling at an expected speed those at a different speed, be it higher or lower, cause difficulty in the brains of the other road users as they are an unexpected occurrence. They will assume vehicles are travelling at certain speeds and pull out, or in front of people, and this could catch you out. Another problem is that, if things do go wrong, and they do, it increases the likelihood of you getting hurt. Any impact straight into a solid object in excess of 80km/hr is invariably fatal. And if it's not, recovery time is long.
I won't be able to ride again for 18-24 months. I'm not sure how I'll feel about exceeding the speed limit then. I imagine I'll probably be unable to resist the feel of the big bikes. But I will be doing so now with the realisation of how much it hurts when you hit something, and how long it takes to come back afterwards. At 50, let me tell you, it isn't as easy to recover as it was when I was 18.
Fire away with the hate if you like. Or engage positively. Either way, you can't ignore, or change, physics.

And I to my motorcycle parked like the soul of the junkyard. Restored, a bicycle fleshed with power, and tore off. Up Highway 106 continually drunk on the wind in my mouth. Wringing the handlebar for speed, wild to be wreckage forever.

Fuck up Simon. You're part of the fucking problem by piss poorly representing motorcyclists, in that you aren't pushing for every license holder to face mandatory training (we need to import trainers) or have the license taken off them.
Jesus titty fucking Christ. I KNOW you would be a body Corp president.

Oh yeah.
The BEST PLACE TO POSITION YOUR BIKE IS THE RIGHT TYRE TRACK.
I never said you need to always be there. It's a STARTING POSITION that offers the most options for escape.
Are you Skidmark?
Serious question. You're special needs cunt, never ever give advice again, you are an waste of oxygen.
Yeah, and those riders that refuse can be dealt with and will eventually be eradicated for all intents and purposes.
Look to Germany and what is required to be a license holder.
Till you half arse fucking pussies actually have something that will make a difference that vast, eat a bag of clocks ya fat cunt.

The fuck makes you think that I'm in charge? You mistake me for someone else, and your ignorant polemic is not only disproportionate but also way off target.
I'd love to be able to cancel all licences and make everyone sit new, harder ones, but we all know that's unrealistic. It would be nice, though, to have empty roads, until the economy collapsed.
You need to calm down and think about how to actually solve problems rather than create them mate.
