Those things can move faster than you’d think, too. I nearly hit a huge snapping turtle driving one night, I honesty thought a stump had fallen off a truck or something at first. The red eyes shining in the headlights were the only reason I knew what it was. Turned the car around to get a better look, maybe get a picture, and it was gone. In less than a minute.
I got a turtle while driving a bus one day. I thought it was just a small pile of leaves until I was about ten feet away. With 35 kids in the back, no way I’m swerving at all.
I actually heard the crack when the front tire rolled over it.
