　　Karl Benz would possibly be shocked at the continued popularity of his invention. Our desire for cars has grown to a point where there is now around one car for every 11 people in the world. Reasonably, you may think that more cars mean more road accidents. But, as ever, numbers tell the truth.

　　Take the UK as an example. In 1950, a few years before I was born, there were

　　4. 4 million vehicles in Britain, one for every 11 people. In 2011, there were 34 million vehicles, eight times as many, and more than one for every 2 people. There were 5, 012 deaths on UK roads in 1950, but by 2011 the number of deaths had dropped by 63%.

　　If we translate these figures into the chance in a million of dying, or micromorts(百万死亡率), there was an average of 102 micromorts per person per year in 1950, dropping to just 31 micromorts per year in 2011. Or to put it another way, each 100, 000 vehicles in 1950 were responsible for 114 deaths, but by 2011 they were responsible for only five deaths.

　　Almost all of the richer nations have followed this pattern, in spite of traffic increasing. In the 30 years between 1980 and 2009, deaths on roads fell by 55% in Australia, 69% in France, 63% in Britain, 54% in Italy and 58% in Spain. But deaths slightly rose in Greece.
