Fun fact: The faster a car travels, the bigger the spacing between the cars gets. That’s necessary to leave enough distance for emergency stops.
While the speed increases linearly, the spacing increases with the square, meaning at double the speed, the spacing quadruples, which in turn means that throughput (number of cars per hour) halves.
This is the reason why many regions use electronic speed signs to drop the speedlimit lower when there’s congestion. Because it increases throughput and thus reduces travel times.
The optimum speed for high throughput is 30km/h.
Counterintuitive as it might be, drivers should be all for 30km/h speed limit in cities, because it would make them get to work faster.
You can cite an infinite amount of proven facts and studies, car brains will never accept your „communist propaganda“. This whole discussion is too emotionally loaded to be based on facts.

That’s also the fastest speed before sharply increasing the likelihood of fatality in pedestrian collisions

That’s when you then turn it around to them.
“We must drive 30 km/hr to show these bastards who’s boss!”.
Another related fun fact: Larger vehicles are harder to see around, so people have to leave even more distance which reduces throughput.
