生理唤醒，测量为心率和皮肤电导水平，在单任务高速公路驾驶（只是驾驶），驾驶和与几个基于语音和视觉手动的信息娱乐用户界面交互时，驾驶和参与多个级别的认知工作量参考任务（n-back）时，以及在单任务（非驾驶）条件下参与相同的认知工作量参考任务时记录。单任务高速公路驾驶被发现产生的生理唤醒水平在相同的范围内的相对较高的要求2回任务在非驾驶条件下。虽然自动变速器、动力转向以及气候控制、隔音和其他舒适功能等持续创新降低了驾驶的明显需求，但这些发现表明，在被认为是“只是驾驶”的过程中，对资源的剩余需求可能比许多人意识到的要高。引入的纵向和横向控制驾驶员辅助功能的各种实施方式在多大程度上改变了这种动态，这在很大程度上是一个悬而未决的问题。
Physiological arousal, measured as heart rate and skin conductance level, was recording during single-task highway driving (just driving), while driving and interacting with several voice-based and visual-manual infotainment user interfaces, while driving and engaging in multiple levels of a cognitive workload reference task (n-back), and while engaging in the same cognitive workload reference task under single-task (non-driving) conditions. Single-task highway driving was found to produce a level of physiological arousal in the same range as that of the relatively highly demanding 2-back task under non-driving conditions. While continuing innovations such as automatic transmission, power steering, as well as climate control, sound proofing and other comfort features, have reduced the overt demands of driving, these findings suggest that the remaining demand on resources during what has been thought of as “just driving” may be higher than many realize. The extent to which various implementations of longitudinal and lateral control driver assistance features being introduced change this dynamic is largely an open question.
