Perhaps 6-8 years ago, the US DOT and NHTSA published a statistic online that identified a thoroughly horrifying situation. Put simply, it said that the chances for every young person in the USA being involved in a serious-injury or fatal road crash at some point in their life is an astonishingly-high “fifty-fifty.” At that time, I looked at my four American step-daughters and wondered which two — statistically speaking — it might be. That statistic, however, very swiftly disappeared off the Internet.
Now, however, I also have six American grandchildren, and just today — August 11, 2017 — another statistic has been published on Facebook by NHTSA which very effectively renews my concerns. It said exactly this:

If the chances “of being in an alcohol-impaired crash [are] one in three over the course of a lifetime,” then clearly that original 50:50 scenario for involvement in any type of serious-injury or fatal crash still holds true for every younger person in America!
