This is standard motoring journo clickbait.
There is not a hope in hell that speed limits will be increased and the entire premise that ‘speed doesn’t kill’ is not supported by the science.
The claim that vehicles are newer and safer because they have new technologies is also pretty shaky:
- Blind spot warning became mandatory in 2023
- Lane assist became mandatory in 2024
- Adaptive cruise control is not mandatory
41% of vehicles registered in NSW are more than 11 years old

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.

Actually the biggest difference there is modern tyres. These are considerably better than those in the 70s - for an easy visualisation compare MotoGP lean angles and cornering speed from that era to what even consumer sport touring motorcycle tyres can handle these days (they weren’t cornering so comparatively slow for no reason, the tyres were the main limiting factor).
You also have modern suspension making a marked improvement on road handling, ABS making it so a chimpanzee can get the best braking without skidding, and in the last decade or so ESC has been making a notable difference to stability under braking and swerving. All together the average modern car will outbrake and outhandle an average 70s car by a long shot, particularly when not driven by an expert.

Except if you fit the unknown retreads that happened to be on special when you needed tyres, and have manufacturing dates from some years ago.
Worse than driving on black ice.
