Hi Peter,

Even Sapolsky never mentions the cerebellum, the part of the brain providing the mechanism for unconscious manifestations of childhood experience, good or bad.

When the industrial revolution blew apart what had since the beginning of our species been  a stable adult community for the child to grow up in, juvenile crime and destructive adolescent behavior exploded.

Adults went to work, leaving the children, in many cases, home alone.

Skills for adulthood, always watched and imitated,  no longer steered the child through puberty and adolescence.

Elementary school should have stepped forward, filling the gap, but didn't.

It's not too late.  beginning driving lessons in 4th grade at age 9, for example, will, with each lesson, pass internal models through to the cerebellum.  When the student reaches driving age, internal models of the legal, proper, appropriate, way to drive will unconsciously steer the driver, virtually eliminating the thousands of driving accident deaths suffered by teenagers each year.

The money no longer spent on teenage driving accidents for one year will have paid for auto-simulators.

Self driving cars for the average person will not enter the market until 2050s.  Thousand of lives could be saved before then.

We MUST address teaching skills for adulthood, no longer observed at home, in elementary school.
