一项自然主义的实验使用仪器自行车从超过驾车者那里收集邻近数据。骑手位置与超越距离之间的关系与普遍认为的相反，因此，骑手距离道路边缘的距离越远，距离越来越近的车辆通过。此外，戴着自行车头盔导致超车时的交通越来越近。大型车辆的专业驾驶员特别有可能留下狭窄的安全利润。最后，当（伴侣）实验者戴着一条长发假发，以便他从后面出现女性时，驾驶员在通过时留下了更多的空间。总体而言，结果表明，驾车者在相遇期间对骑自行车的人出现的各个方面表现出行为敏感性。鉴于先前对驾驶员对骑自行车的人的态度的研究，我们建议驾驶员接近骑自行车的人的驾驶员使用外观来判断骑手的特定可能性，并相应地改变了他们的超越。但是，可以从外观中推断出骑自行车的人的瞬间行为的程度是值得怀疑的，因此，根据这种外观，驾驶员改变其传球接近的趋势可能对事故概率有影响。 （c）2006 Elsevier Ltd.保留所有权利。
A naturalistic experiment used an instrumented bicycle to gather proximity data from overtaking motorists. The relationship between rider position and overtaking proximity was the opposite to that generally believed, such that the further the rider was from the edge of the road, the closer vehicles passed. Additionally, wearing a bicycle helmet led to traffic getting significantly closer when overtaking. Professional drivers of large vehicles were particularly likely to leave narrow safety margins. Finally, when the (mate) experimenter wore a long wig, so that he appeared female from behind, drivers left more space when passing. Overall, the results demonstrate that motorists exhibit behavioural sensitivity to aspects of a bicyclist's appearance during an encounter. In the light of previous research on drivers' attitudes to bicyclists, we suggest drivers approaching a bicyclist use physical appearance to judge the specific likelihood of the rider behaving predictably and alter their overtaking accordingly. However, the extent to which a bicyclist's moment-to-moment behaviour can be inferred from their appearance is questionable, and so the tendency for drivers to alter their passing proximity based on this appearance probably has implications for accident probability.
