The answer both to why has a car seat been so successful, and why this may someday be adopted or not, lies in a story that my dad told me, relating to when he was a doctor in the U.S. Air Force in England. And this is a long time ago: you were allowed to do things then you can't do today.
这个答案可以解释为什么汽车安全座椅那么成功， 也可以解释为什么我的新发明可能某一天会被应用，当然也可能不会。 这个答案包含在下面这个我爸爸讲给我听的故事里，当是他是一个大夫， 在英国的美国空军驻地工作。这是很久以前的事了。 那时候，你还可以有很多自主权。
