Deer Strike

I guess, if you assume zero depth perception (the extreme case), an approaching
vehicle will appear either stationary, or slowly moving sidewise, gradually
increasing in size. An oncoming tiger is a) non-wheeled, i.e. has a lot more
apparent relative motion against the background, and b) doesn't have
a constant speed of advance, which also contributes to its non-stationary
appearance. All in all, if you're dumb enough not to be able to logically
infer the nature of the motion from increasing size and noise, lack of
depth perception can make it look distant and non-threatening kind of curious
thing moving sidewise and not towards you. Deer need help. I wonder if
there's anything simple you can do that will instantly reveal your 3D nature
to the deer, some sort of a clue for the depth-perception-impared.

I do know deer have a 'rods and cones' thing going on in their eyes. Nature sacrificed some depth perception so it could bulk up on movement receptors.

The resulting depth perception /issue/ makes avoiding oncoming motorcycles difficult for Bambi.

Interesting. Does it also make avoiding oncoming tigers difficult?
