Clearly, all of this will have some effect on congestion and road capacity. Accidents themselves cause as much as a third of congestion (estimates vary a fair bit and depend whether you're talking about highways or city centres), even if there are no changes from different driving behavior. How much changes over all, though - how much more traffic can a highway hold? How much more quickly do you get to school in the morning if you drive at the same speed but don't have to stop at every stop sign just in case there's someone there? We'll find out.
In the Media: Individual attitudes are influenced by the images of other groups in the media and the press. For instance, many Serbian communities believed that the western media portrayed a negative image of the Serbian people during the NATO bombing in Kosovo and Serbia. This de-humanization may have contributed to the West's willingness to bomb Serbia. However, there are studies that suggest media images may not influence individuals in all cases. For example, a study conducted on stereotypes discovered people of specific towns in southeastern Australia did not agree with the negative stereotypes of Muslims presented in the media.
