Earlier quoted context omitted.

What? It’s the children who get run over by speeding assholes.

that might be news to you but those people don't give a shit about speed limits

Arrest them, take away their cars. Repeat until they do "give a shit".

Good. Everywhere in the cities the speed limit in residential areas should be 30km/h and 60km/h for everything else. No need for higher speeds in dense urban environments.

In Sweden it's commonly 30-50km/h for inner city streets, I think it's a good sweet spot, 60km/h has 44% more kinetic energy than 50km/h, and since most time lost in urban areas is due to stoppage (traffic lights, intersections, etc.) there's minimal change on travel times at the lower speed.

The article don't have a good picture of a small road. Here's an example https://kuruma-news.jp/wp-content/uploads/2023/02/20230214_g... Usually these roads are so small, you can barely fit a car and maybe one pedestrian on one / each side. And these streets are quite common in residential area. As in the picture, usually there are light poles along the pedestrian street. the pictures pole is pretty small but normall…

Your edit reminds me of some years ago at a conference an American was asking in a boasting way what some European people thought of cybertrucks. I don't know if he owned one or worked on them or just liked them, but he seemed to want some praise on it. They tore into it including how big it was relative to narrow European streets and that they wouldn't be legal to sell in Europe. The guy didn't talk to them after that

Maybe in Japan it will be effective. Since their "zone 30" creation was apparently a success, it seems probable that people will generally comply. My experience in France differs. I live in a French town where the default speed limit is 30 km/h instead of the national 50 km/h. In the street where I live, the drivers that willingly (sometimes they can't overtake bikes and slow cars) observe that limit are a tiny minor…

Street bumps are much more efficient in lowering speed than either "automated controls" or "manual controls". You (plus neighbours, probably) could petition your council to put one (or several) on your street.

I'm surprised the limit was so high on those narrow, low visibility streets to begin with. In many EU countries the limit is 30km/h even on streets that are double the size, if they're in residential neighborhoods to increase pedestrian safety.

Not a lot at announcement and even less now, not seen one in the UK (they aren't road legal).

Halved? So you could go 60 on narrow city streets?

In Netherland, the speed limit in cities used to be 50, and even in the 1980s, people were complaining that that was too fast. Most residential streets have been 30 (or less; the street I grew up in had a limit of 5 or 10 km/h) for some time, and Amsterdam recently made it the default for all streets with only exceptions for the biggest thoroughfares. They've also experimented with closing some of those thoroughfares.

Cars are bad for cities. It's a simple fact. The big advantage of cities is that everything is within walking or cycling distance, and the density is perfect for dense public transport. The only use for cars is to get out of the city.

Low speed limits make cars safer, but they also encourage safer forms of transportation. It's great to see this insight take hold in more countries.

Its ironic, because the biggest danger in Amsterdam are cyclists doing well over 60 inside town narrow streets.
