>Building 1,500 kilometres (900 miles) of "2+1" roads—where each lane of traffic takes turns to use a middle lane for overtaking—is reckoned to have saved around 145 lives over the first decade of Vision Zero. Basically translates to: "this substantial increase on costs (3 lanes instead of 2, +50%) is going to save the lives of 15 people per year". It is really praiseworthy for a country to just go for it and put people first. A human life is truly invaluable but very few countries actually account for them as such; on most other countries "15 dead" would simply just not be worth the investment.
