The Welsh parliament has passed a law bringing down the speed limit on all residential roads and busy streets to 20 mph (30 km/h). Not everyone is pleased.

    This doesn’t really apply because harm to a pedestrian during an impact isn’t a linear scale.

    There are sharp decreases in fatalities and permanent injuries, particularly to children who are often the ones hit in neighbourhood streets, below about 30 km/h so there’s a strong incentive to have drivers travelling at speeds no higher than that to avoid child murder and maiming due to inattention.

    Below those speeds, and given that people do often belatedly apply the brakes when they’re driving recklessly there is a much weaker case for further reduction in speed limits. At least until car geometry changes again to make them even deadlier /shrug shrug

      Now, you see - that’s a completely different argument.

      And also validates my point, all speed limits are tradeoffs.

      Don’t get me wrong though, 20mph/30kph limits are commonplace where I live and honestly surprised to hear that it wasn’t everywhere.

      For improved safety in the future we’ll need better driving assistance systems in the cars, and finally to replace humans altogether.
