Given what a deer carcass looks like after being hit by someone going 70 or so mph (to say nothing of what the car, driver and passengers look like), it may not be a smart thing to be walking along an interstate.
They do walk along their version of interstates in Mexico, and in Mexico, the speed limit is merely a suggestion. There are a lot of crosses put up along the limited access roads in Mexico.
