This is a well-written, easy-to-understand book. An historical account of how humans perceive certain conditions, and their reactions and responses to the same. Olson writes that "collisions represent a system failure, the cause of which may be found in any component or combination of components." As investigators, we have learned to depend strictly on the technical aspects of accidents, and the investigation of same, i.e., the road, vehicle, product liability, etc. Olson opens up a whole new aspect on perception and response. It is an excellent book for the serious motor vehicle collision investigator.

The greatest strength of this book is Paul Olson's constant theme that life rarely reflects the test conditions . . . . It will make a useful addition to the library of any accident investigator who wants or needs to go beyond determining speed.

The material is logically organized and easy to follow. Each chapter stands on its own, and can be read to get an excellent overview of any of the specific topics. This is an excellent and easily understood book.
