There's no reason not to eat roadkill. In the past, many states in the US would use such meat to supplement the meat in prisons. When you dress it out, use only the parts that aren't mangled.

Of course, a true pavement pancake is a different story.

Another true story:

It was hunting season in Ohio, and a woman came in to use the phone at the library where I was working. We let her -- she'd just smacked into a deer with her pickup and wanted to call the sheriff.

A deputy sheriff came and found the deer laying in the ditch. The deputy did what had to be done.

Some days later the woman came in again and I learned what happened.

After the deputy had shot the deer, she asked what to do. The deputy -- another woman -- conferred with her and sent our library patron up the to hardware where she obtained a hunting license and a deer tag. They tagged the deer, loaded it into the pickup, and drove to the local Fish and Game Check Station. The woman took the deer to a local butcher, who over the next couple of days prepared and wrapped about a hundred pounds of good meat from it.

Just after she'd finished loading the packages of meat into the freezer, her husband came home. From his deer hunting trip with his friend. For the sixth year in a row, neither he nor his buddies had shot a deer. She just kept quiet and sent him down to get some meat from the freezer for dinner....
