This is a good coffee table book with excellent photography, but is very thin on information for people who may actually drive some the routes described.
As you would expect in a coffee table read the information is presented thematically, with no attempt to provide a geographic finding aid which would be useful to narrow down trip locations beyond the entire planet. Maps are small, and little detail is offered about food, accommodation, weather, local politics, or even where to locate a vehicle.
Driving any of these trips would take considerable additional research. In areas I am familiar with I noticed that some of the authors are quite happy to subject themselves to huge stretches of interstate or bald prairie that many will describe as mind numbingly dull.
This is a pretty book which might give you an idea about a trip, but as a tool to assist people actually considering the drives, a reader is left with more questions than answers.
