Someone else commented here that when hit by a car at 50 kph, there's a 20% chance of survival, and at 30%, there's a 90% chance of survival. So in the best case, this might save 35 lives per year. Not to mention the reduction in noise, pollution, and damage to vehicles. I think that's easily worth it.
I posted a graph in another comment here about the drastic effects such a small speed change has for survival rate.
This can have a huuuge impact.
Keep in mind the massive number of minor and serious injuries that accompany that stat.
It would seem likely to be a massive economic drain, quite apart from the sheer waste.
Here in NZ for a road toll of 300, 4000ish serious injuries and 30k minor injuries, the cost was $4.6 billion in 2019.
That doesn’t cover lost tax take etc. Reducing that number down is obviously helpful.

It's ok if you guys feel this is normal but for me it´s too much. Cities were vibrant places to share experiences that today are a complete mess of zombies taking pictures for the trendy social network. And this is just one more drop to make cities more soulless and "2030 ready" for people who does not really exist. I cannot say this is useless, it's just another politically correct decision to deal with. Too much already for me at least.
Like, was an important part of your urban experience traffic noise, or the sound of ambulance sirens going to pick up a dead pedestrian? I'm genuinely a bit baffled by where you're coming from here.
