The first and only live armadillo I ever saw made contact approximately .05 seconds later with the engine mounting cross member of my 1984 Trans AM at ~80mph. I remember thinking "damn, those suckers are fast" (just shot out in road). felt like hitting a cinder block.
A buddy of mine was cruising cross Texas interstate at substantial speed in his 911 Porsche at dawn in 1992. The last thing he remembered was the passing blur of black shadows on the road. Amazingly his low profile car undercut and rocketed a black angus over the car! Good old Jack Butts lived to tell that tale...
