Amuses me every time I hear of someone being "chased" by a snake.
Snakes have poor eyesight, at best can only see approx 2m in distance in front of them. They mostly rely on movement to see, that`s why it is recommended to stand still if you come across a snake. 99% of the time the snake will be long gone before it sees you (or you see it). Without external ears, they can`t hear airborne sound, and "hears" by detecting vibrations in the ground. Most of the time it will know your coming before you even know it is there.
If someone has been "chased", it`s more likely the person has become between the snake and its comfort / safety zone. And the person doing the running has run towards the place the snake wants to go, making it appear the snake was chasing them. The land speed of a snake is somewhat slower than a human, and would think it impossible for a snake to actually chase down anyone or anything.
What really annoys me is when you hear of news reports of snake "attacks". A snake will bite in self defence, they don`t go out of their way to seek out humans and "attack" them. Normally a snake won`t bite anything it doesn`t want to eat (unless its in self defence), otherwise it would be going after every roo, wombat, cow, sheep, goat and anything else that moved out in the paddocks / wild.
I think a fear of snakes tends to exaggerate peoples stories of encounters. The bigger the snake, and the more venomous, and the faster the snake always makes for a better story.
