Speed kills. It’s the message that we’ve had driven home for decades by law enforcement and the government. But it’s time to have a serious discussion about speed limits in Australia without the hysterics and put some cold, hard facts into the debate.

I'm not opposed to 130 km/h speed limits on the sorts of very remote highways where you'll usually encounter like 20 vehicles max in an hour. But busy motorways where you measure vehicles per minute, like the Bruce Highway between Brisbane and the Sunshine Coast, or the motorways up and down the east coast between Brisbane and Sydney, despite being the most well-maintained, are just far too busy for such high speeds to be appropriate. It's more appropriate on the roads that head out west with road trains.
But a much, much more sensible policy, if we're looking at changing how we set our speed limits, would be to lower the speed limits within cities. Local streets and shopping high streets should be 30 km/h. Other roads should be adapted to be better for pedestrians and cyclists, including narrowing the amount of space given to cars if necessary, and a commensurate lowering of speed limits from 60 or 70 to 40 or 50. That's still more than your average travel speed in a car is anyway thanks to traffic and lights. So you'd be adding safety and comfort for people outside of a car*, without actually negatively affecting those inside a car very much.
* and I do so hate how so many people talk about modern cars as being so much "safer" than old ones, while they completely ignore the increased danger they pose to cyclists and pedestrians—especially children. Modern cars are not safer.

Sure here’s one this “journo” conveniently left out. Stopping distance is a function of speed and the relationship is essentially exponential. At 110km/h the stopping distance is approximately 113-143 meters. Hope you see that roo quick enough.
This average covers all ages, situations (fatigue) etc. I seriously doubt the average commuter can see, interpret and then apply brakes in 0.1s. Average reaction times for a video game is over 200ms lmao.
As a motoring enthusiast, I love to go fast, but there's a number of problems:
a faster speed limit will not result in more cars per minute on a given road. As speeds increase, cars have to be more spread out.
by no means are Australian roads are in a condition for ultra high speed limits. Our way of fixing pot holes is very touch and go. We have bumbs and undulations. On the Autobahn, they replace the entire tarmac, not just fill in a hole.
a lot of our car fleet is not safe or designed to go 130kmh. A lot of older 4wds with big tyres, these were never designed to go fast. They have tiny brakes. In Germany a roadworthy is massive, and older cars are taken off the road.
a faster speed will result in more CO2 emissions. Cars (especially SUVs), get worse fuel mileage above 100kmh as wind drag becomes a greater burden. EVs get exponentially worse range at high speeds.
a lot of our car fleet tows caravans. That are not designed for that speeds.
in NSW were their L platers can't go faster than 90, this will be a massive speed differential.
we have unique hazards such as wildlife and unlit highways that makes fast driving extremely dangerous.
faster driving leads to more lethal crashes, especially in poor weather.
There's an economic trade-off for everything. It's not that we can't have it happen, but roads like the Hume Highway and Pacific Highway will need to be completely redone with a widespread flattening of the road, gentler corners, constant surveillance of kangaroos and wombats on the road and a massive road maintenance workforce who can rapidly fix entire sections of the road.
This will require raising taxes or diverting funds, not worth it, especially when you have a road network that is at least 10 times the size of Germany, and with a quarter of the population.
I've never complained about being behind a car that's doing the speed limit in the right lane. In fact, they're ideal because your get there in the fastest possible time using the least possible fuel.
A car in the rightmost lane doing the speed limit – by definition – cannot be an obstruction.
What pisses me off is cars with overreading speedos that think they're doing the speed limit. Everyone should check theirs. 100% of new cars are wrong.
I'd happily sit on 130 if that's the posted speed. That's about 4500RPM in top gear for me... which is probably not the best for economy.
The claim that vehicles are newer and safer because they have new technologies is also pretty shaky
A significant proportion of cars do have the mentioned features though, blind spot monitoring is a nice easy one to notice and you'll see a lot of cars do have it when you're driving around.
Even without these specific features though modern cars are much safer than cars were when our speed limits were set. This even applies to cars now considered old - my own car for example now qualifies for historic rego and can drive quite safely at 130km/h (and is both less likely to get into a crash and much more survivable in the event of one than any 70s car).
Back when the 100km/h limit was set this was actually a fast speed for the cars and roads of the era. Now it is not - speed limits have become a recommended speed rather than anywhere near the limits of safety (assuming average car and normal conditions). Highway/freeway limits in particular are well due for an increase rather than the decreases (literally and effectively) they keep receiving.
Have human reflex’s been updated since the speed limits were set? The distance a car travels in the time it takes for you to see something like a pedestrian while driving, recognize it as a hazard, press the brake pedal, and then for the car itself to respond to your command and stop is one of the primary determinants of a safe speed.
About the only thing on that front that’s changed since the 70s have been improved breaks, but that’s been largely balanced out by heavier vehicles so stopping distance hasn’t been radically improved.
Higher speed still means longer stopping distances, longer distances between vehicles, wider minimum safe curves, shorter reaction times, more energetic collisions, and a larger gap between the speed limit and the maximum possible speed in rain, snow, and fog, which have remained nearly identical since the vehicles of the 50’s.
Vehicle on vehicle collisions have gotten more survivable when things do go wrong, but surely we should rejoice that people are more likely to survive a trip rather than increasing speeds until just as many die as they did before? I mean personally I would much rather live to see my destination than save a few minutes.
This also all just talking about highways, on all other streets and roads the six year old running out into the middle of the road has not gotten any more crashworthy than they were in the seventies, and slight reductions in speed have been proven to result in massive increases in pedestrian survivability.
It really shouldn't be, but there has been a lot of money and effort expended over the years here to make people believe speed is the root of all evil. Combine that with the fediverse attracting a larger proportion of who are ideologically against any form of personal motorised transport and anything involving cars or bikes can become surprisingly contentious even before you bring speed into the mix.
I could live with that tradeoff, but I'd have to see the regional speeds raised first because I don't believe that would actually happen given how risk-averse our governments are. Instead regional roads keep getting their speed limits lowered and any suggestion of raising them raises cries of outrage - typically from people who aren't even in the area and who get scared driving on roads without streetlights.
