I've heard this counter argument so many times and it's nonsense. There were 1560 road fatalities recorded in 2021. You're still going to see a huge reduction by implementing this law. Besides, as a drive you should anticipate these problems before they occur that lead to hitting the accelerator.
You know the chances of a pedestrian dying from being hit by a car reduces dramatically when going 30 compared to 40 and 20 compared to 30 and so on? That's what we gain from it.
There's no tracking or privacy concerns wrt speed limiters. Do you own a mobile phone? PC? Take your concerns elsewhere.
Err, okay. So let's ditch this silly idea because it won't work for <1% of the driving population.
There's some classic resistance to change going on here, peeps.
