Abstract: Vehicle feedback includes steering feel, engine noise and most other aspects of what the driver can perceive through their normal interaction with the vehicle. Ten car drivers took part in an on-road study to explore the relationship between vehicle feedback and the concept of driver situational awareness (SA). It was shown that drivers of older generation vehicles with higher levels of vehicle feedback have statistically better SA than drivers of modern vehicles. The results are considered important from a primary safety viewpoint as poor SA is reported to be a greater cause of accidents than improper speed or driving technique.

Keywords: car design; driver performance; vehicle feedback; driver situation awareness; vehicle design; steering feel; engine noise; vehicle safety.
