Carl Posted: 12/4/2012 5:44pm PST When I first became an auto safety engineer (1965)0 data indicate that driver-adulthood began at age 25 - generally after the stabilizing influence of marriage. I confess that it worked for me. Now the data seems to say that has risen to ~30. I believe that the overall improvement, especially for seniors, is because they can afford to buy cars with newer crash-avoidance and crash-survival features. When I began crash testing, a ten-mph run into a concrete barrier was considered surely fatal. Today the driver should be able to walk away from a 30 mph hit. Crash fires are now exceedingly rare (except on TV). I am now 82+ years old and I won't deny that my abilities have gone bad. But, when I started, I did not really want to live Carl Posted: 12/4/2012 5:46pm PST Oops - pressed POST too soon. I did not really want to live past age 55 because then high-G driving was a no-no.
