... there are no simple 'right' answers for most web design questions (at least not for the important ones). What works is good, integrated design that fills a need--carefully thought out, well executed, and tested.

Ranney, Thomas A. and Pulling, Nathaniel H. (1989): Relation of Individual Differences in Information-Processing Ability to Driving Performance. In: Proceedings of the Human Factors Society 33rd Annual Meeting 1989. pp. 965-969.

Fifty subjects ranging in age from 30 to 83 participated in a closed-course driving test and in laboratory tests of information processing. Driving tests included responding to traffic signals, selection of routes, avoidance of moving hazards, and judgment at stationary gaps. Lab tests included measures of perceptual style, selective attention, reaction time, visual acuity, perceptual speed and risk-taking propensity. Analyses were conducted to determine how well lab measures predicted driving performance. Results revealed different patterns of correlations for different age groups. For younger drivers (30-51), lab measures generally showed no association with measures of driving performance. For older drivers (74-83), measures of information-processing were associated with overall rated driving performance, while measures of reaction time showed strong correlations with objective driving measures. The results suggested that different mechanisms are utilized by drivers of different ages, and that the slowing of reaction time associated with aging has effects on driving skills related to vehicle control.

Ranney, Thomas A. and Pulling, Nathaniel H. (1987): Stopping Performance in Familiar and Unfamiliar Vehicles. In: Proceedings of the Human Factors Society 31st Annual Meeting 1987. pp. 762-765.

Lack of vehicle familiarity is a contributing factor in motor-vehicle accidents. It may also contaminate results in experiments where subjects are required to drive unfamiliar vehicles or driving simulators. An instrumented driving range, including a signalized intersection, was developed to evaluate driving performance in subjects' own vehicles. Fourteen drivers completed approximately fifty laps of the one-half mile closed course in their own vehicles and in an unfamiliar passenger van. Their task was to stop at the stop line following the change of the traffic signal from green to yellow. Brake reaction time, smoothness of deceleration, approach speed, and stopping accuracy were recorded. In the unfamiliar van, brake reaction times were faster and drivers were more likely to stop considerably before the stop line than in their own vehicle. Deceleration was slightly smoother in the unfamiliar van. Individual differences in approach speed were stronger than differences associated with vehicles. Overall performance was influenced more by the position of the vehicle at yellow onset than by vehicle familiarity. Results were interpreted as suggesting heightened driver awareness in the unfamiliar vehicle. Implications for the safety of drivers in unfamiliar vehicles are discussed. The use of unfamiliar vehicles in driving performance research and problems of data analysis resulting from the use of drivers in their own vehicles are also discussed.
