Winged creature with 15-foot wingspan and red eyes circling my car on the highway

I know how this sounds. I was on I-77 near Point Pleasant around 9 PM. A massive dark shape began circling low over my car — I could see its wingspan blocking out streetlights as it passed. Humanoid shape, no feathers, dark leathery wings. But the eyes were what I can't shake: two bright red points that seemed to glow from inside. It kept pace with my car for almost two miles before banking away toward the river. I'm not from here but a local mechanic at the gas station I stopped at immediately said "you saw the Mothman, didn't you." I didn't know what that was at the time. Now I've done the reading. I believe him.
