There's a form of casual violence that kills 1.25 million people a year (3 times more than malaria) and injures up to 50ODI roads cover million more. 90% of the deaths are of poor people (usually men) in poor countries. No guns are involved and there's lots of things governments can do to fix it. But you'll hardly ever read about it in the development literature, although road safety did make it into the Sustainable Development Goals (as did everything else, it has to be said) - targets 3.6 and 11.2 for SDG geeks.
So hats off to ODI (again) for not only painstakingly building the case for taking action on a major cause of death and misery in poor countries (see below), but also exploring the politics and institutions that so far have prevented governments from taking action.
