I always use a good rule of thumb is that if it could have been in my high school library’s collection, it is probably too old for a modern teen collection. (For those keeping score, I graduated in the late 70s.) Seat belts only became mandatory for manufacturing in 1968. How about other changes in safety? How about cell phones? Speed limits? Unleaded gasoline?
As the auto engineer husband would say, “safety is not a joke”.
