Hasbeen, old buddy are you alright ? Not someone else's fault ? How un-australian.
Seriously, if only more people could understand the concept of self-discipline I'm sure we'd have far less roadkills rather than killer roads. I'm guilty myself of misjudging on the road & I only blame myself. I recall our local roads when you needed all your concentration to negotiate potholes & washouts. No accident had ever occurred to to speed. As soon as the road was sealed we had a fatal within a few weekes & several more since.
Our local Doctor rolled his 4x4 & landed on a log which crushed his roof. Because he didn't have his seat belt on he was flung across his seat & escaped injury. From his seat to the roof ended up at half a metre. Imagine if had been in a sitting position with the seat belt on.
Of course I'm not saying seat belts aren't good in most cases.

It is raining.
Not long ago on this part of the highway it meant get ready, be strong.
It meant for those who must attend the coming smash to get the special shirt on.
The one that held us together, let us pretend it was ok.
Still this rain may not kill, but it will hurt smashes happen more often in rain at dawn and middle of the night, sleep time faster to get home time.
Forget to adjust to road conditions time.
as anti said, new concrete roads are European standards, maybe not as many lanes, we keep putting an extra one on.
But if we constructed for a distant future say 15 years, we would have less for other roads.
Road construction and repair is far too important to be used as political fodder about one road, at the expense of every other.
No road still in place,as built ever killed or hurt any one.
Like the Fonz we can find a thousand reasons to not say we got it wrong.

I've been driving in 3 states and 2 teritories for 46 years. Accidents = 2 [ acts of god, unavoidable - hit by another driver in tail ]. speeding fines = 3 all in QLD - all BS by corrupt means. That said; back in 60's I drove dad's car [ no seat belts ] at 170KPH on open limit brand new Ballarat freeway. Top car [ Fairlane 500 ] top tyres, perfect day, straight road, little if any traffic. Did that make me a bad driver ?.4 things make an accident - the road, the weather, the car, the driver. If one of these things isn't perfect, your chances of accident magnify. THIS FORMULA HAS KEPT ME ALIVE and speed signs don't mean squat. Do you know the formula for speed advisory signs ? [blk/yell] It's the fastest safe speed in the worst conditions [ weather/road] with the best tyres. Drive accordingly and you'll be jake.

Well said Pepper, I regularly used to average well over 70 miles/hour, & occasionally up to the 80s driving interstate trips in the cars of the day, in the 60s, with never an accident, or even a scare. Overnight interstate trips were quite easy.

However you do want to be careful of those advisory speed signs in boarder areas. I often flit backwards & forwards across the NSW Qld boarder on roads inland from the coast.

In NSW in good conditions, in a nice car I usually double the recommended speed, & find that right up at the top end of the speed one would want to go, on the public road. Take 10Km/H off that & you have a reasonable cruising speed.

After crossing the boarder you want to make that speed double less 20Km/H or so. The Queensland recommendations are definitely higher than those in NSW, allowing less scope to drive faster than those recommended speeds. A number of people have given themselves a fright, when they found themselves going a bit fast for the corners, when they had not known of the difference.

It is easy to get sucked in, when you have been driving with one recommended level for an hour or two, then don't even notice you've crossed the border.

I well come those two posts but in a way it proves my point .
I remain a petrol head, even unwell can drive without a stop for 5 or 6 hours.
But can every one? should I.
No road still in its serviceable condition ever killed.
No acts of God except fire flood breakdown.
We share the road with drunks drug affected under skilled and speeders not in control of the car.
I always drive to conditions, and my known ability,if conditions are bad forget the skill.
On black on yellow first appearing I was a kid privileged to see the cars testing each corner.
Those drivers along with a red x round Australia competitor told me just that, after that speed it was unsafe.
73 human body's removed from cars trucks all types while I worked I stopped counting.
AS 28 DIED IN ONE YEAR 26 THE ONE BEFORE HOW MANY?
Drivers good bad ugly are the one in charge.

We must be careful to understand what we should and should not say about this theme.
But I need to say it.
A very long time ago I was monitoring CB radio, as an emergency monitor.
Mobile phones if they existed,and I am not sure, could not link to police and all services quickly.
A truck went past my door interfering with my receiver, I switched to his frequency and over heard him .
He was lost in abusing the motorist behind him.
He rolled the truck 500 meters down the road.
I rang the police ext and raced down to help.
He was sitting shaken but unhurt on the gutter two mates with him.
They, while I sat with them concocted a story about a phantom car, coming the other way.
Running him of the road.
My load slipped,a whole host of reasons got air, but that is the one they settled on.
Highways kill? maybe not.
