Distracting Miss Daisy

A British professor who works in both the US and UK makes the case that the overabundance of unnecessary and frequently contradictory road signs in the US actually contribute to traffic accidents and fatalities. In short, by forcing us to constantly look to signs for guidance (and to avoid penalties) instead of trusting our instincts and training (especially in adverse weather conditions), we are more likely to be distracted, confused, and unsafe on the roads.
