Which is worse, war or cars? The latest edition of New Scientist magazine has a short item comparing the annual number of deaths caused by the two.
Cars win hands down, with twice as many - at least according to the correspondent in this issue, who bases his figures on World Health Organisation data. They show that 1.2 million people around the world (mostly pedestrians and cyclists) are killed directly by motor vehicles every year. About the same amount again die from traffic-related air pollution.
So perhaps the government could set up some sort of scheme where you can scrap your car and get £2000 towards financing a war.
