- normally result in an adaptation of behaviour on the tactical level,
- such that constant safety margins are maintained.
When drivers are not able to adapt behaviour on the tactical level for whatever reason, for example,
- because they are intoxicated with alcohol or drugs or
- impaired by fatigue or drowsiness, or
- because they are inexperienced, or they overestimate their driving skills,
the risk of traffic accidents greatly increases. So the model has a direct link with driver safety. It also explains why vehicle factors aimed to improve safety often don't result in safety improvements in practice.
