参考答案：D

解析：[听力原文]Many drivers do little more than look over the hood while driving. You must train yourself to fix your eyes so that they can see not only the road ahead of you but objects on each side of you and behind you. Concentration is one of the most important elements in safe driving. The driver’s seat is no place for window-shopping, nor it is a place for a tired driver or worried one. Driving an automobile is a full-time job.

[分析]： 语义推理判断。 题干问许多司机会出什么错误 根据原文The driver’s seat... nor it is a place for a tired driver or worried one可推断，若司机疲劳或烦恼焦虑时驾驶会引发事故。因此D说许多司机常犯的错误是疲劳驾车或焦虑驾车是正确的。[解题关键] 1)有关汽车驾驶的常识有助于正确解题；2)根据各个选项中关键词定位到原文相关处，可帮助听者做出迅速判断。
