Although a little heavy in places this is a very interesting book. It covers a wide range of driving research, from drink-driving, the effects of drugs, fatigue, age and the variety of 'interfaces' that can get in the way of the act of driving itself. It also covers how the latest research believes the eyes and the brain work to see, or fail to see hazards.
A large number of research articles are referred to, with the authors reasoning as to why the research is or is not useful. There are explanations of statistics for some studies and why they can say whatever you wish, depending upon what you are trying to prove.
Oddly enough I found the section on fatigue a little tiring to read, but the section explaining why hands-free 'phones and non hands-free are just as dangerous as each other was interesting. The section on elderly drivers and why they aren't as dangerous as young drivers (except for problems at junctions) was also very well written.
The final section, about new developments in car technology and why they should be a cause for concern gave pause for thought too.
An excellent book, although its probably best to read it in small bursts.
