In the interest of accuracy, I did some quick research. I compared Automobile deaths to hunting deaths for 2004 and 2006 the closest years I could find numbers for:

"Worldwide it was estimated in 2004 that 1.2 million people were killed (2.2% of all deaths) and 50 million more were injured in motor vehicle collisions"
...........................................................

"Hunting accidents with firearms, despite the large gun ownership in the U.S. and numerous game seasons in most states, remain relatively rare and do not appear to be increasing. (Huiras, et al, 1990"
...........................................................

Based on my research, I now believe that all cars and pedestrians should be blaze orange, and hunters are good to go with camo.
