Fast on the track, safer on the road

The book contains many tips that have helped me to ride better on the racetrack.
For the street many of the tips are also useful. On the racetrack make faster, safer on the road. However, the main target audience of the book are in my opinion people who want to improve their driving skills on the racetrack. For only road drivers who want to buy only one book, the book of Prof. mirror may be better suited. The more advanced you are, the more you will but can start with the books by Keith Code.
I have the American original. The German translation I found not so great.
