The picture is of an Asiatic Black Bear, also known as a Moon Bear. I’ve never heard the referenced Buffalo Bear before.

Are they mutually exclusive? What prevents a tourist from volunteering?

In answer to your over simplistic question, for starters how about… road surface suitability for grip & condition, repair records, gradient, safety barriers, signage, lighting, weather conditions? runaway escape lane? CCTV to check other driver involvement?
