I went off to try and find some statistics from a few decade's ago, and go on about how we've doubled the population (and people probably drive more now than then aswell) yet maintained the same number of accidents, but came across some statistics from 2010 showing that 37% of fatalities involving speed (exceeding the posted limit or driving too fast for conditions) involved drivers aged 17 to 25. Another interesting statistic is that over the last 5 years, 80% of the drivers in that age group involved in fatal accidents were considered at fault.
Another interesting statistic is that in 2010 only 22% of all crashes involved speed, whereas 30% of young driver fatalities involved speed, against the 5 year average before that of 38%. Not sure what to make of that.
