然后Ｓ这个人说：那说明我们这里的ｓａｆｅｓｔｄｒｉｖｅｒ基本不是ｔｅｅｎａｇｅｒ

a) “说明ｍａｎｙ　ｓａｆｅｓｔ　ｄｒｉｖｅｒｓ会买Ｘ这种车”。

b) Ｘ车是ｓａｆｅ　ｃａｒ

P's statement equals to => X car-buyers are not teenagers;
S=>All safetest drivers are not teenagers;
如果要使两个人的说法都正确, then there must be some overlap between P and S. Another word that some safetest drivers(>0) are X buyers.

a) many safetest drivers (>0) buy X. => There is overlap between P and S. So a) is sufficient.
b) Safe car just out of scope.
