The Association of British Drivers (ABD) has claimed that the Driving Standards Agency ignored its proposed contributions to the latest revision of the Highway Code.
According to the body, it put forward measures to advise cyclists and pedestrians about how to use their mobile phones when around other vehicles.
In addition, it recommended that inexperienced drivers be urged to take up Pass Plus courses in order to strengthen their road skills.
Similar, the ABD suggested that the Code offer greater clarification as to the difference between single and dual carriageways.
"It is clear that the government is not interested in using the pool of knowledge about real-world driving that exists within the ABD, simply because we campaign against its dogmatic anti-car policies," commented group spokesman Nigel Humphries.
The latest edition of the Highway Code was released in September 2007, with the first version launched in 1931.
