Personally, i always have a self preservation respect for wild animals that are bigger than me, and especially ones that have body piercing horns, teeth or antlers.
This seems to be beyond many people, especially those filming with a smartphone. But i'll happily watch their comeuppance on Youtube.
You get this on Exmoor. You'll be sat in a carpark eating a sandwich admiring the ponies 20 yards away then a group of idiots will walk right up to them and cause them to run off so nobody can see them.
