One of the craziest things that we as a society do is give teens licenses to operate death machines, which in some communities, are known as "cars". (Full disclosure: I am extremely afraid of driving and do not have my licence.) While people get into crashes at any age, teens account for 30 per cent of motor vehicles crashes in the United States even though they only represent 14 per cent of drivers. In Australia, the rate of road deaths for young adults is 56 per cent higher than for all age groups. This makes sense, considering teens are inevitably new and inexperienced when it comes to driving.
