In many public schools, there are dress codes that prohibit students from wearing tank-tops, tube tops, and shorts that are deemed "too short," as these could distract male students.
If men can be this easily distracted by women's bodies, then this raises a variety of safety concerns.
Many busy highways have billboards that use sexually suggestive imagery of women's bodies.
Women also often go about their everyday lives near roadways wearing tanktops and short shorts.
If straight men (and men of other sexual orientations who are attracted to women) can be distracted by the mere sight of a woman's thigh, then it is a public safety hazard to allow them to operate vehicles that weigh thousands of pounds at up to 75mph past these inevitable distractions.
