I doubt that many people are collecting roadkill on a 75mph 6-lane divided freeway though, since I can't really think of any safe way to collect it.

But even if you could collect it, hitting anything small at that speed will completely pulverize it, and hitting anything larger will seriously hurt the vehicle's occupants, so it's probably best to stick to smaller roads.
