Clean air cuts accident levels
Well if I wasn’t just bestowing the virtues of electric cars last week... This week I find out that a 30% drop in nitrogen dioxide levels could cut accidents by 5%. The link was spotted by a clever PhD student at the London School of Economics (LSE). Through studying data from between 2009 and 2014, he saw that in areas where nitrogen dioxide concentration rose by just one microgramme per cubic metre, the average number of accidents increased by 2%. Unsurprisingly, the link was particularly prominent in cities. The student, called Lutz Sager, put some of the increase in accidents down to the physical distractions that pollution could cause, such as limited visibility. But his main theory was that the increase in poor air affected the drivers’ health and ability to carry out mental tasks. And as keen a driver I am, I can believe that. Driving through a busy city at rush hour, in the rain, perhaps when you don’t know where you’re going… It’s exhausting! Just because we jump in the cars e...
