Japan's halving the speed limit to 30km/h on all narrow city streets. That's a pretty dramatic change - presumably it's about safety and reducing accidents, especially in residential areas? Curious what the actual reasoning is and whether this is going to make a real difference or just annoy drivers.
It's pretty much the safety angle - lower speeds mean shorter stopping distances and way less severe injuries if someone does get hit, which matters a lot in areas with kids and pedestrians around. Japan's been pushing this for a while because their accident stats in residential zones were pretty grim, and honestly the data does show that dropping from 60 to 30 does make a real difference in outcomes, even if drivers find it tedious.
