3 main elements of the highway mode
1 human element
2 vehicle
3 environment
a broad based body knowledge that deals with the driver’s natural abilities, learned capabilities, and his motives and attitudes.
Driver personality
can reveal the need for mechanical and visual aids to correct most natural human deficiencies.
Physical and psychological tests
offer a formal way to measure traits, feelings, beliefs and abilities that can lead to people’s problems.
Psychological tests

The driver’s goal of moving from one point to another is achieved through three tasks:
control
guidance

refers to the driver’s task of selecting a safe speed and path on the highway, which is essentially a decision process.
